To show your coordination, you try to toss a ball straight upward so that it just barely touches the ceiling (position is given in meters and time is given in seconds). What initial velocity is required? In this Exploration the acceleration of the ball is -9.8 m/s². Calculate this initial velocity and then test your answer bytyping the initial velocity in the text box and clicking the "set velocity and play" button. Restart.
