A ball is shot vertically upward from the surface of another planet. A plot of y versus t for the ball is shown in the figure, where y is the height of the ball above its starting point and t = 0 at the instant the ball is shot. The figure's vertical scaling is set by y. = 33.0 m. What are the magnitudes of (a) the free-fall acceleration on the planet and (b) the initial velocity of the ball? 0. 1 2 4 t (s) (a) NumberT9.16 Units (b) Number 21 Units (w) (
