Physics
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 below, where y is the height of the ball above its starting point and t = 0 at the instance the ball is shot. The figure’s vertical scale is set by ys = 30.0 m. (a) Write expressions for the displacement and velocity of the ball as functions of time. (b) What is the magnitude of the freefall acceleration on the planet? (c) What is the magnitude of the initial velocity of the ball?
