Car A, which is travelling at a constant velocity of 15 ms-1, passes Car B, which is stationary, at time t = 0. At the instant that it is being passed, Car B begins to move, accelerating at a constant rate of 0.1 ms-2 in the direction in which Car A is travelling. At what speed will Car B be travelling as it passes Car A (in ms-1)?
The Attempt at a Solution
Ok so I know that this is a relative velocity question? so the relative velocity will decrease by 0.1 per second. But I then get stuck, im having trouble understanding the situation I think]
