A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.
<h3>What is Uniformly Accelerated Motion?</h3>
Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.
A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.
v² = u² + 2 × a × s
v² = (0 m/s)² + 2 × (9 m/s²) × 240 m
v = 66 m/s
where,
- v is the final speed.
- u is the initial speed.
- a is the acceleration.
- s is the displacement.

Answer:
Acceleration, 
Explanation:
It is given that,
Initial speed of the aircraft, u = 140 mi/h = 62.58 m/s
Finally, it stops, v = 0
Time taken, t = 2 s
Let a is the acceleration of the aircraft. We know that the rate of change of velocity is called acceleration of the object. It is given by :
So, the acceleration of the aircraft is 
and the car is decelerating. Hence, this is the required solution.
Answer:
1. stay away from the people and control the habits
The contact force is indeed caused by "Contact".
Air resistance is basically a type of friction, which is apparently present providing two object contact.
The rest selections are all interaction force, which is not necessarily caused by contact.
Answer:
Explained below.
Explanation:
Yes cars have antennas.
Now there could be an antenna for listening to radio stations which could be regular radio stations or even satellite radio stations.
Also, there could be antennas used for GPS navigation or some form of communication with other vehicles that possess that type of antenna.
