A ball is thrown vertically upward, starting at y = 0, with a velocity of 15.0 m/s.
(a) Calculate the maximum vertical displacement of the ball.
(b) Calculate the time required for the ball to reach its highest point.
(c) What is the ball's acceleration when it is at its highest point?
(d) How long does the ball take to reach the point y = 0 after it reaches its highest point?
(e) What is its velocity when it returns to the level from which it started (y = 0)?
Is there no part of this you can figure out?
