A car accelerates to 150m/s in 3 seconds from rest (a)what is the acceleration? (b)what distance did the car travel

A car sits on an entrance ramp to a freeway, waiting for a break in the traffic. Then the driver accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 20 m/s 145 mi/h2 when it reaches the end of the 120-m-long ramp. (a) What is the acceleration of the car? (b) How much time does it take the car to travel the length of the ramp? (c) The traffic on the freeway is moving at a constant speed of 20 m/s.What distance does the traffic travel while the car is moving the length of the ramp?

A driver wants to see how fast his car can go, so he goes out to the salt flats where he can drive a very long way in a straight line over level ground. Suppose he starts from rest and travels 400.0m with a constant acceleration of 8.00m/s2. (a) How long did this take? (b) How fast was the car going at the end of this trial?

A stone is thrown upward with a speed of 7 m/s from a height of 20 m. (acceleration due to gravity: 10 m/s2)a) What is the speed (in m/s) of the stone just before it hits the ground? b) How long does it take (in seconds) for the stone to hit the ground?

A stone is thrown downward with a speed of 7 m/s from a height of 20 m. (acceleration due to gravity: 10 m/s2)a) What is the speed (in m/s) of the stone just before it hits the ground? b) How long does it take (in seconds) for the stone to hit the ground?

A jogger accelerates from rest to 3.0 m/s in 2.0 seconds.  A car accelerates from 38 to 41 m/sec also in 2.0 seconds.  A) Find the acceleration of the jogger.  (b) Determine the acceleration of the car.  (c) Does the car travel farther than the jogger in 2.0 seconds?  If so, how much further?

A hot rod car can accelerate from 0 to 60 km/h in 7.0s. (a) What is its average acceleration during this time? (b) How far will it travel during the 7.0s, assuming its acceleration is constant? (c) From rest, how much time would it require to go a distance of 0.39km if its acceleration could be maintained at the value in (a)?

A car traveling 56.0 km/h is 24.0 m from a barrier when the driver slams on the brakes.The car hits the barrier 2.00 s later. (a) What is the magnitude of the car’s constant acceleration before impact? (b) How fast is the car traveling at impact?

A person walking covers 0.5m in 1.0s.  She accelerates and in the next 1.0s they cover 1.5m.  (a) What is her rate of acceleration and (b) how far would she travel if she continued to accelerate at this rate for 4.0s?

A car traveling 56.0 km/h is 24.0 m from a barrier when the driver slams on the brakes. The car hits the barrier 2.00 s later. (a) What is the magnitude of the car’s constant acceleration before impact? (b) How fast is the car traveling at impact?
