Suppose you throw a ball straight upward; it rises, then returns to your hand (a) Calling the point where it leaves your hand the origin and upward positive, make a plausible sketch of its position (vertical height) x(t) versus time t from the instant after it leaves your hand till the instant before it reaches it again.
(b) From your x(t) plot, make a sketch of the ball’s velocity v(t) versus time.
(c) From your velocity plot, sketch a plot of the ball’s acceleration versus time.
(d) Does your plot suggest that the ball’s acceleration is zero at the top of its flight?
