A stationary police car is passed by a driver driving at a constant speed of 130 km / h.

A stationary police car is passed by a driver driving at a constant speed of 130 km / h. The police officer catches the fast-moving driver after 750 m at constant acceleration.

a) Draw a plot of position time over the period of action of each vehicle.

b) How soon will the police car catch the driver?

c) The acceleration required for the police car

d) What is the speed of the police car at the point of capture?
