Question

As you walk briskly down the street, you toss a small ball into the air. If you want the ball to land in your hand when it comes back down, should you toss the ball straight upward, in a forward direction, or in a backward direction, relative to your body? straight upward in a forward direction in a backward direction Choose the best explanation from among the following: You have to throw the ball in the direction you are walking. If the ball is thrown straight up you will leave it behind. The ball moves in the forward direction with your walking speed at all times.

Explanation / Answer

A) as you are walking, holding the ball, it has the same velocity you do. as long as you are walking with a constant speed, you must only throw it straight upwards since the ball's horizontal velocity already matches that of your body and that answers part B as well: the ball has the same velocity in the horizontal direction as does your body imagine the same situation but you are sitting in a car traveling at a constant speed: you would toss the ball straight up, not forward or backward
