Question

1. Starting from rest, it took you 12 seconds to accelerate your car to 24 m/s at a constant acceleration. Find your acceleration.

2.A prototype car starts from rest and accelerates at a constant rate to 60 m/s in 5.1 seconds. How much distance did the car travel during the 5.1-second accelerated motion?

3. A speeding driver noticed a police car parked about 443 m in from of him on the side of the road and reduced his speed at a constant rate for a duration of 10.2 seconds as he drove past the police car, at the legal speed of 35 m/s. What was the car's acceleration (include a negative sign in your answer)?

4.A car was parked on the side of a hillside road at the top of a hill. Unbeknown to the owner, its parking brake failed and a tremor from nearby construction set it in motion with negligible initial speed down the hill. Assume the acceleration was constant down the hill, the car was given a speed ticket by a traffic camera at the foot of the hill, which measured the speed of the car at 28 m/s. The video recording showed the car took 35 to slide down the hill. How long is the road on the side of the hill?

5. An object is experiencing a constant acceleration. At time 2 s, it is traveling at 43 m/s. At a later time 7, it is traveling at 50 m/s. Find its acceleration.
