A sports car is going 40.0m/s. It approaches a stationary police car stopped at the side of the road. When the sports car is still 210 meters from the police car, the police car accelerates at 3.0 m/s^2.

a) How long will it take the sports car to pass the police car?
b) How far will the police car have travelled when the sports car passes it?
c) If the police car were to maintain this acceleration, how fast would it be travelling when it overtakes the sports car?
