This problem should be solved using the principles of Energy Conservation found in Chapter 3. You should ignore friction. Write the speed of a ball launched vertically from the ground using the following: Write the kinetic, potential and total energy of a 1kg ball being launched vertically from the ground at the speed of 30. Write the kinetic, potential and total energy when the ball no longer is moving up but comes to rest just prior to falling back to earth. This is it's maximum height. What is the ball's maximum height in meters
