Acceleration due to gravity 10 m/s2

• 1. A penny is dropped with zero velocity from the
  top of a 150 m building. What will be the
  velocity as it reaches the ground?
• 2. A ball is thrown straight upward with an
  initial velocity of 25 m/s.a. What is the
  velocity at the high point in its motion?b. How
  much time it takes to reach the high point?c.
  How high is the high point?d. What is the
  velocity of the ball 3 seconds after its throw?
• 3. A pitcher throws a baseball at a speed of 90
  MPH, horizontally. The pitchers mound is 60 ft
  from home plate.
• What is the speed in m/s?
• What is the distance to home plate in meters?
• How much time is required for the ball to reach
  home plate?
• How far does the ball vertically drop during the
  throw?
