Solve the all parts of given question:
Question: A speeder traveling at a constant speed of 34.7 m/s races past a stopped patrol car on the interstate. A patrol car pursues from rest with constant acceleration of 2.22 m/s2 until it reaches its maximum speed of 52.8 m/s, which it maintains until it catches up with the speeder. Both cars are always traveling west on the interstate.
Part A: How long does it take the patrol car to reach a speed of 52.8 m/s if it starts moving just as the speeder passes?
Part B: How long does it take the patrol car to catch the speeder if it starts moving just as the speeder passes?
Part C: How far does each car travel during the period when the parol car starts moving till it catches the speeding car?
