A policeman travelling 60 km/h spots a speeder ahead , so he accelerates his vehicle at a steady rate of 2.22 m/s^2 for 4.00 s, at which time he catches up with the speeder.

a) How fast was the policeman travelling in m/s?

b) How fast is the police car travelling after 4.00 s? Give answer in both m/s and km/h?

c) If the speeder has a constant velocity, sketch the motion of both the speeder and police car on a speed vs. time graph?
