(a) 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? (b) Choose the best explanation from among the following: I. If the ball is thrown straight up you will leave it behind.

II. You have to throw the ball in the direction you are walking.

III. The ball moves in the forward direction with your walking speed at all times.

Solution: (a) If you want the ball to land in your hand when it comes back down, you should toss the ball straight upward. (b) When a person tosses a ball upward while walking, the horizontal component of velocity of the ball and the person will be the same. So the ball moves in the forward direction with your walking speed at all times when you toss the ball straight upwards.

Therefore option III is correct.

Chapter 4 Two-Dimensional Kinematics Q.2CQ

A projectile is launched with an initial speed of v0 at an angle θ above the horizontal. It lands at the same level from which it was launched. What was its average velocity between launch and landing? Explain.

Solution:
