A burglar's car in operation alone townA has a start with an acceration of 2m/s^2. A police van came after 5sec and continue to chase the burglar's car wit uniform velocity of 20m/s.find the time take in which the police patroj van will overtake the burglar's car.

Answer 1

solve for t when the two distances are equal:

(1/2)(2)t^2 = (20)(t-5)

You will find that 20 m/s is the minimum speed at which the patrol car can catch the burglar.
