Problem 2-95 Linear Kinematics

A camera is set up to take photographs of a ball undergoing vertical motion. The camera is 5.2m above the ball launcher, which can launch the ball with an initial velocity of 17m/s upward. Assuming that the ball goes straight up and straight down past the camera, at what times will the ball pass the camera?


Let us first of all have a drawing which summarizes the physical problem. Which is correct?
