Two cars A and B are moving in the same direction along a straight horizontal road. At time t = 0 they are side by side, passing a point O on the road. Car A travels at a constant speed of 30ms^-1. Car B passes O with speed of 20ms^-1, and has a constant acceleration of 4ms^-2
At which time the car A overtake car B if the speed of the car B is 20 m/s^-1 and has a constant acceleration of 4m/s^-2 whereas, car A has a constant speed of 30 m/s
No idea in how to begin.
When one is being overtaken, the displacement is the same for the two cars at the same value of time.
Construct the two equations for displacement in terms of t using SUVAT and solve them simultaneously.
