Physics Chase Problem

Question

A motorcycle is following a car that is traveling at constant speed on a straight highway. Initially, the car and the motorcycle are both traveling at the same speed of 23.0 m/s, and the distance between them is 60.0 m After t1 = 2.00 s, the motorcycle starts to accelerate at a rate of 4.00 m/s^2 . The motorcycle catches up with the car at some time t2.

What is t2-t1?

Answer 1

suppose t2-t1=t

1/2*4*t^2=60

so you can solve t
