3. The marble's trajectory was constantly being changed by running into the ring, forced it to move along the shape of the ring.

4. Once the ring was removed, the marble's momenum kept it going in a straight path as the ring was no longer forcing it to turn.

Explanation:

Answer:146.8983 grams

Answer:

Objects move according to their net force, or the total amount of force acting on them. Balanced forces are just that, balanced. An object with balanced forces will not move because the opposing forces will cancel each other out. However, if there are unbalanced forces, the object will move in accordance with the force that is greater. When moving though, there is always friction. Whether you be underwater, on the ground, or in the air there is always friction on the Earth. (Besides vacuums, of course.)

Force is equal to mass x acceleration.

With that you can find the forces of the object if you know its mass and acceleration.

Explanation:

The motion of an object can be described in many ways, including path, speed, velocity, and acceleration.

Answer:

2.125 m/s^2

Explanation:

Use Newton's second law: Force equals mass times acceleration, F = ma. You know the force (51 N) and you know the mass of the mower (24 kg). Remembering that a Newton is the same as kg-m/s2, solve for acceleration:

F = ma

51 kg-m/s2 = 24 kg * a

2.125 m/s2 =a

If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

Given the data in the question;

Net External Force; [tex]F = 51N[/tex]

Mass of the Mower; [tex]m = 24kg[/tex]

Acceleration; [tex]a = ?[/tex]

To determine the acceleration of the mower, we make use of the equation from the Newton's Second Law of Motion:

[tex]F = m\ * \ a[/tex]

Where F is the force exerted, m is the mass and a is the acceleration.

But then, we know that; ( A newton is the same thing as  [tex]1 kg.m/s^2[/tex] )

Hence, Our Net External Force; [tex]F = 51kg.m/s^2[/tex]

We substitute our values into the equation to find acceleration "a"

[tex]51kg.m/s^2 = 24kg\ *\ a\\\\a = \frac{51kg.m/s^2}{24kg} \\\\a = 2.125 m/s^2[/tex]

Therefore, If a net external force of 51N is extorted on a 24kg lawnmower parallel to the ground, the acceleration of the mower will be 2.125 m/s².

Explanation:

Ff

Answer: 36.257 m/s

Explanation:

The vertical and horizontal components of a projectiles motion are completely independent of each other. The only thing they share is the amount of time in the air. Because they are independent, the acceleration of gravity cannot affect the horizontal acceleration. This means horizontal acceleration is 0. If the acceleration is 0, this means the velocity does not change horizontally. So the final velocity of the x component is equal to the initial.

Now if you actually imagine these two vectors, it forms a right triangle. So you can use the Pythagorean Theorem to find the resultant vector.

[tex]a^2+b^2=c^2\\18.3^2+(-31.3)^2 = c^2\\c = 36.257 m/s[/tex]

Answer: 510 in Newton’s and 115 lbs

Explanation:

Considering the definition of weigh, Lisa weighs 0.5096 N or 0.1146 pounds.

Mass is the amount of matter that a body contains, while weight is the action exerted by the force of gravity on the body. That is, weight is a measure of how much force gravity exerts on the mass of an object.

The mass of an object will always be the same, no matter where it is located. Instead, the weight of the object will vary according to the force of gravity acting on it.

Weight can be calculated as the product of mass and acceleration due to gravity:

W=m×g

In this case, you  know:

Replacing in the definition of weigh:

W=0.052 kg×9.8 m/s²

Solving:

W= 0.5096 N

1 newton equals 0.2248 pound. Then W=0.5096 N= 0.1146 Pounds

Finally, Lisa weighs 0.5096 N or 0.1146 pounds.

Answer : Noble Gases do not readily form compounds because they are chemically stable with 8 valence electrons.

Explanation :

Noble gases are the chemical elements that are present in group 18 in the periodic table.

The elements are helium, neon, argon, krypton, xenon and radon.

They are chemically most stable except helium due to having the maximum number of 8 valence electrons can hold their outermost shell that means they have a complete octet.

They are rarely reacts with other elements to form compounds by gaining or losing electrons since they are already chemically stable.

Hence, the noble Gases do not readily form compounds because they are chemically stable with 8 valence electrons.

A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory.

Answer:

d= 45 m

Explanation:

speed = distance / time

15= d/ 3

d= 45 m

Answer:

(a). The rocket's velocity is 117.6 m/s.

(b). The rocket can reach at maximum height is 940.8 m.

(c). The velocity the instant before the rocket crashes on the ground is 135.7 m/s.

Explanation:

Given that,

Acceleration = 29.4 m/s²

Time = 4 sec

(a). We need to calculate the rocket's velocity

Using equation of motion

[tex]v=u+at[/tex]

Put the value into the formula

[tex]v=0+29.4\times4[/tex]

[tex]v=117.6\ m/s[/tex]

We need to calculate the maximum height at the moment fuel ends

For the value of x₁

Using equation of motion

[tex]x_{1}=ut+\dfrac{1}{2}at^2[/tex]

Put the value into the formula

[tex]x_{1}=0+\dfrac{1}{2}\times29.4\times4^2[/tex]

[tex]x_{1}=235.2\ m[/tex]

We need to calculate the value of x₂

Using equation of motion

[tex]v^2=u^2-2gx_{2}[/tex]

Put the value into the formula

[tex]0=u^2-2gx_{2}[/tex]

[tex]x_{2}=\dfrac{u^2}{2g}[/tex]

Put the value in to the formula

[tex]x_{2}=\dfrac{117.6^2}{2\times9.8}[/tex]

[tex]x_{2}=705.6\ m[/tex]

(b). We need to calculate the maximum this rocket can reach

Using formula for height

[tex]H=x_{1}+x_{2}[/tex]

Put the value into the formula

[tex]H=235.2+705.6[/tex]

[tex]H=940.8\ m[/tex]

(c). We need to calculate the velocity the instant before the rocket crashes on the ground

Using equation of motion

[tex]v^2=u^2+2gh[/tex]

Put the value into the formula

[tex]v=\sqrt{2\times9.8\times940.8}[/tex]

[tex]v=135.7\ m/s[/tex]

Hence, (a). The rocket's velocity is 117.6 m/s.

(b). The rocket can reach at maximum height is 940.8 m.

(c). The velocity the instant before the rocket crashes on the ground is 135.7 m/s.

Answer:

The average speed form A to C is 72 miles/hour

Explanation:

Average Speed

If an object travels a distance d in a time t regardless of the direction, the average speed is the quotient of the distance over the time:

[tex]\displaystyle \bar v=\frac{d}{t}[/tex]

Lily travels from A to C in two steps:

First, she takes ta=3 hours from A to B at va=60 miles/hour. The distance traveled in that time is:

da=va*ta

da=3*60 = 180

da = 180 miles

Then she takes tb=2 hours to travel from B to C at a speed 50% increased with respect to va, thus:

vb=150*va/100=1.5*60=90

vb=90 miles/hour

She travels a distance:

db=2*90=180 miles

The total distance traveled is

dt=180 + 180 = 360 miles

And the total time taken is

tt= 3 + 2 = 5 hours

Thus, the average speed is:

[tex]\displaystyle \bar v=\frac{dt}{tt}[/tex]

[tex]\displaystyle \bar v=\frac{360}{5}[/tex]

[tex]\displaystyle \bar v=72\ miles/hour[/tex]

The average speed form A to C is 72 miles/hour
