A motorist traveling at 30 m/s passes a parked police car. At the instant the motorist passes the police car, the police car starts chasing the motorist with an acceleration of 3 m/s^2.
How far does the police car have to travel to catch the motorist?

The car is caught when
(3/2)*t^2 = 30 t.
Solve for the nonzero t and use that to compute the distance travelled.
