Given parameters:
Speed of car = 50m/s
Time of travel = 5minutes (300s)
Unknown;
Distance of travel = ?
To solve this problem, we need to understand how speed relates with distance and time.
Speed is a physical quantity. It is the distance traveled divided by time taken.
Speed = [tex]\frac{distance}{time}[/tex]
So,
Distance = speed x time
Input the parameters and solve for the distance;
Distance = 50m/s x 300s
Distance = 15000m
The distance covered during this time interval and speed is 15000m
HELP PLEASE: Which option is an example of an object that has potential energy followed by an object that has kinetic energy?
A the fuel in the tank of a car | a car that is parked in a parking lot
B A battery in an electric car | a car parked in the middle of a hill
C A ball held over a person's head | a ball rolling on the floor
D A person riding an elevator | a person in an elevator at the top floor
Answer:
C
Explanation:
Potential energy is energy that something has when its not moving. Kinetic energy is energy in motion. A ball held over a persons head isn't moving, meanwhile a ball in motion is using kinetic energy.
C)A ball held over a person's head | a ball rolling on the floor.
What is an object that has potential and kinetic energy?Objects may have each kinetic electricity and capacity electricity at an equal time. An item may be accelerated above the ground (have capacity electricity) and be shifting at the identical time (and now have kinetic electricity). A baseball, a plane, and a flying chicken are all easy examples of this.
Is light potential or kinetic energy?A rushing bullet, a walking person, and electromagnetic radiation like mild all have kinetic energy. Some other example of kinetic strength is the strength associated with the constant, random bouncing of atoms or molecules.

A cell phone weighing 80 grams is flying through the air at 15 m/s. what is the kinetic energy?
Answer:
The answer is 9 JExplanation:
The kinetic energy of an object can be found by using the formula
[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]
where
m is the mass
v is the velocity
From the question
m = 80 g = 0.08 kg
v = 15 m/s
We have
[tex]KE = \frac{1}{2} \times 0.08 \times {15}^{2} \\ = 0.04 \times 225[/tex]
We have the final answer as

A ball is thrown upwards into the air with an initial velocity of
17.5 m/s. What is the maximum height that the ball traveled
during that time (assuming there is no air resistance). Round your
answer to two decimals places.
Answer:
y = 15.61 [m]
Explanation:
To solve this problem we must use the following kinematics equation. We must bear in mind that the acceleration of gravity is negative since the direction of gravity is opposite to the direction of motion.
[tex]v_{f} ^{2} = v_{i} ^{2} -(2*g*y)[/tex]
where:
Vf = final velocity = 0
Vi = initial velocity = 17.5 [m/s]
g = gravity acceleration = 9.81 [m/s^2]
y = height [m]
The final speed is zero, since the ball reaches the maximum height its speed will be zero since it cannot be lifted up more.
0 = (17.5)^2 - (2*9.81*y)
306.25 = 2*9.81*y
y = 15.61 [m]
what do waves create
Answer:
Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides.
Explanation:
Answer:
Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin. Waves are most commonly caused by wind.

A car traveling south is 200 kilometers from its starting point after 2 hours. What is the average velocity of the car?
А.
100 kilometers/hour south
B.
200 kilometers/hour
C.
200 kilometers/hour north
D.
100 kilometers/hour
Answer:
D) 100 kilometres/hour.
Explanation :
Given -
Displacement = 200 kmTime taken = 2 hrs.To find -
Average velocity of the car.Solution -
★ Velocity = displacement/time
→ V = 200/2
→ v = 100 km/h
Therefore, the average velocity of the car is 100 km/h.

a vector must always have both size and
Answer:direction
Explanation:
A vector must always have both sizes as well as direction, while on the other hand, any scalar quantity such as the mass of an object would only have magnitude but not direction.
What is a vector quantity?The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
Examples of vector quantities are displacement, velocity acceleration, force, etc.
A scalar number, such as an object's mass, would only have magnitude but not direction, unlike a vector, which must always have both quantities and direction.

Think about what you already know. Why might two objects be affected differently if the same strength force is exerted on them?
Answer:Explanation:
If the same strength force is exerted on two objects, but the objects have the different masses, the object with less mass will have a greater change in velocity. ... Forces affect motion because they can change an objects motion.
The reason for two objects being impacted differently even a similar strength of the force is applied/exerted to them:
- Two objects might be affected differently on the application of a force of the same strength owing to the difference in their masses.
The second law of motion by Newton states that the rate of change of momentum of an object is directly proportional to the applied unbalanced force in the direction of the force.However, We know, Momentum = Mass × velocity.Hence, if the masses are different and the force applied is the same, the two objects will move with different velocities.

A shopping cart given an initial velocity of 2.0 m/s undergoes a constant acceleration to a velocity of 13 m/s. What is the magnitude of the carts acceleration if the time is 4.0?
Also if your really smart and have instagram please dm imaswagmeal and help me pls
Answer:
The acceleration is a = 2.75 [m/s^2]
Explanation:
In order to solve this problem we must use kinematics equations.
[tex]v_{f} = v_{i} + a*t\\[/tex]
where:
Vf = final velocity = 13 [m/s]
Vi = initial velocity = 2 [m/s]
a = acceleration [m/s^2]
t = time = 4 [s]
Now replacing:
13 = 2 + (4*a)
(13 - 2) = 4*a
a = 2.75 [m/s^2]

A freeway exit curves with a radius of 30 m and a posted speed limit of 17.5 m/s. What is your radial
acceleration if you take this exit at the posted speed?
Answer:
10.21m/s²
Explanation:
Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:
a(r) = v²/r
Where a(r) = radial acceleration
v = velocity
r = radius of the circular path
According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;
a(r) = v²/r
a(r) = 17.5²/30
a(r) = 10.208333
a(r) = 10.21m/s²

An athlete starts running from rest such that he covers a distance of 5mm in 0.50s with a constant change in velocity per unit time . when will he reach the finish line, if he is running a race of 50m?
Answer:
50 s
Explanation:
Given:
Δx = 0.005 m
v₀ = 0 m/s
t = 0.50 s
Find: a
Δx = v₀ t + ½ at²
0.005 m = (0 m/s) (0.50 s) + ½ a (0.50 s)²
a = 0.04 m/s²
Given:
Δx = 50 m
v₀ = 0 m/s
a = 0.04 m/s²
Find: t
Δx = v₀ t + ½ at²
50 m = (0 m/s) t + ½ (0.04 m/s²) t²
t = 50 s
