how long did it take for the car to come to rest?

A speeder travelling at a constant velocity of 40 m/s passes by a police car that is initially at rest.   Soon afterwards, the police officer starts moving towards the speeder with an uniform acceleration of 5.33 m/s2. How long does it take,  in seconds,  for the police officer to catch the speeder?

An object that moves from rest and accelerates uniformly in a straight line in the direction of the x axis. After 11 seconds, the object has a speed of 70.0 m / s. ,determins the average speed of the object during the 11 seconds.

A runner of mass 50.1 kg stařts from rest and accelerates with a constant acceleration of 1.1 m/s2 until she reaches a velocity of 6.5 m/s. She then continues running at this constant velocity. How long in seconds does the runner take to travel 104 m? 载

A train, traveling at a constant speed of 22.0 m/s, comes to an incline with a constant slope. While going up the incline, the train slows down with a constant acceleration of magnitude 1.40 m/s2. (A) What is the speed of the train after 7.20 s on the incline? (B) How far has the train traveled up the incline after 7.20 s?

A barge is being towed at 16 m/s when the towline breaks. It continues thereafter in a straight line but slows down at a rate proportional to the square root of its instantaneous velocity. If two minutes after the tow line breaks, the velocity is 9 m/s, how far does it move before coming to rest?

The driver of a truck slams on the brakes when he sees a tree blocking the road. The truck slows down uniformly with an acceleration of -5.60 m/s2 for 4.20 s, making skid marks 62.4 m long that end at the tree. With what speed does the truck then strike the tree?

A snowboarder on a slope starts from rest and reaches a speed of 4.4 m/s after 9.4 s. (a) What is the magnitude of the snowboarder's average acceleration in m/s2(b) How far does the snowboarder travel in this time in m

A bullet shot straight up returns to its starting point in 63.7 s. embedding itself 15.5 cm deep in a wooden block. What is the average acceleration the bullet encounters in the block (in standard units)? Answer: Check

A car starts from rest, then accelerates at a constant rate over a distance of 55 m. It then immediately decelerates at a constant rate over a distance of 86 m. The entire trip lasts a total duration of 12.3 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?     4.78 m/s^2, then 3.06 m/s^2     4.47 m/s^2, then 6.99 m/s^2     1.86 m/s^2, then 1.86 m/s^2     6.99 m/s^2, then 4.47 m/s^2
