Predict/Explain You throw a ball into the air with an initial speed of 10 m/s at an angle of \(60^\circ\) above the horizontal. The ball returns to the level from which it was thrown in the time T. (a) Referring to Figure 4–21, which of the plots (A, B, or C) best represents the speed of the ball as a function 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.

ANSWER:
Step 1 of 3
Here from the given plots we have to choose and explain the appropriate plot that matches the motion of the ball.
The ball is thrown with the initial speed of with an angle of
above the horizontal surface and the ball comes back to the initial position in time T.
