The answer (distance) is:
216mThe distance of the truck in the given time is 216 m.
How do you find displacement with velocity and acceleration?
Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
How do you find velocity from acceleration?
Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change in speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h.

Suppose that a particular artillery piece has a range of R=9240 yards. Find the range in miles
Answer:
5.25[mile]
Explanation:
We must remember that the yard is a measure of length of the imperial system and that a Mile is also a unit of length of that system.
Therefore we must use a conversion factor that relates the yard to the mile.
[tex]9240 [yard]*[\frac{0,000568182miles}{1yard} ]=5.25[miles][/tex]

What is the fastest speed at which a tennis ball can cross the net horizontally and still land in the court? From the net to the end line is 12 m, and the height of the net is 1 m. Neglect air resistance and spin on the ball.
A. 0.04 m/s
B. 27 m/s
C. 53 m/s
D. 45 m/s
self note *6
Answer:
B. 27 m/s
Explanation:
The horizontal velocity of the ball is 27 m/s
The given parameters;
horizontal distance, x = 12 mheight of the net, h = 1 mThe time of motion is calculated as;
h = ut + ¹/₂gt²
1 = 0 + (0.5 x 9.8)t²
1 = 4.9t²
[tex]t^2 = \frac{1}{4.9} \\\\t^2 = 0.205\\\\t = \sqrt{0.205} \\\\t = 0.45 \ s[/tex]
The horizontal velocity of the ball is calculated as;
X = uₓt
[tex]u_x = \frac{X}{t} = \frac{12}{0.45} = 26.7 \ m/s \ \approx 27 \ m/s[/tex]
Thus, the horizontal velocity of the ball is 27 m/s

Explain Kinetic and potential energy
Answer:
Energy implies as the object’s capability to perform work. It is something that cannot be created or destroyed but can only be transformed. An object loses its energy, when it performs work, whereas it gains energy when the work is performed on it. Energy is broadly classified as kinetic energy and potential energy. While kinetic energy is the energy which an object contains because of a particular motion.
On the other hand, potential energy is the stored energy, because of its state of rest. As both the two forms of energy are measured in joules, people get easily confused between these two. So, take a read of the article which will help you to understand the differences between kinetic and potential energy.
Explanation:
Hope this helps - Good luck ^w
Answer:
Energy stored in an object due to its position is Potential Energy. · Energy that a moving object has due to its motion is Kinetic Energy.

The correct option is (a) Equal forces
Newton's third law of motion:Newton postulated that whenever objects A and B interact, they exert forces on one another. You put a downward force on the chair when you sit on it, and the chair responds by exerting an upward force on your body. This contact creates two forces: one force on the chair and one force on your body. These two forces—also known as the action and reaction forces—are covered by Newton's third law of motion. There is an equal and opposite response to every action, according to the formal statement of Newton's third law.There are always two forces acting on the two interacting objects, according to the statement's interpretation. The amount of the force known as the action and reaction forces—are covered by Newton's third law of motion. There is an equal and opposite response to every action, according to the formal statement of Newton's third law.There are always two forces acting on the two interacting objects, according to the statement's interpretation. The amount of the force exerted on the first and second objects are equal. In contrast to the force acting on the second item, the force on the first object is operating in the opposite direction.

The table shows experimental data of the magnitude of four forces exerted on a 2kg object as it slides across a horizontal surface. Which of the following could represent the magnitude of the net force that is exerted on the object? Select two answers.
Answer:
6N and 10N
Explanation:
The forces acting along the horizontal axis arw the horizontal force applied and the frictional force.
Frictional force is a force that opposes the horizontal force (moving force)
First we need to get the sum of force along the horizontal as shown
\sum Fx = Horizontal force - frictional force
\sum Fx = 8N - 2N
\sum Fx = 6N
Hence one of the magnitude of the net force exerted on the object is 6N
For the forces along the vertical component;
The forces are the weight, force of gravity(acting downward) and the normal force acting upward
Given
Weight = mass × acceleration die to gravity
Weight = 2×10 = 20N
Normal force = 10N
\sum Fy = (weight)-normal force
\sum Fy = (20)-10
\sum Fy = 20-10 = 10N
Hence the other net force acting on the object is 10N
The required options are 6N and 10N

1. During an accident investigation, a detective measures the skid marks that a car
left to determine how fast it was initially moving before stopping when it hit a
light pole. The detective measures the distance to be 40 meters. The detective
receives the car's braking acceleration to be 4.57m/s2 from the manufacturer's
manual. Help the detective by solving how fast the car was initially going before
he hit the light pole? Someone please help I’ll give you a brainlest
Answer:
19.12 m/s.
Explanation:
The following data were obtained from the question:
Final velocity (v) = 0 m/s
Breaking Acceleration (a) = – 4.57 m/s²
Distance (s) = 40 m
Initial velocity (u) =.?
The initial velocity of the car can be obtained as illustrated below:
v² = u² + 2as
0² = u² + (2 × –4.57 × 40)
0 = u² + (– 365.6)
0 = u² – 365.6
Collect like terms
u² = 0 + 365.6
u² = 365.6
Take the square root of both side
u = √365.6
u = 19.12 m/s
Therefore, the car was initially moving at 19.12 m/s.
