Help on Physics kinematic problems please?
1. Car 1 moves eastward with a constant speed of 20 m/s. Car 2, at rest on the side of the road, accelerates at 2 m/s squared to the east at precisely the instant Car 1 is beside it. How long does it take for Car 2 to catch up to Car 1?
2. Car 1 moves to the east with a constant speed of 20 m/s. Car 2 moves to the west with a constant speed of 30 m/s. How far from the start of Car 1 do the cars meet?
