· · CE Predict/Explain You throw a ball into the air with an initial apeed of 10 m/s at an angle of 60° above the horizontal. The ball returns to the level from which it was tin-own in the time T. (a) Referring to Figure 4-21, which of the plots (A, B, or C) best represents the speed of the bal) as afunction of time? (b) Choose the best Explanation from among the following:

I. Gravity causes the ball’s speed to increase during its flight.

II. The ball has zero speed at its highest point.

III. The ball’s speed decreases during its flight, but it doesn’t go to zero.
