Because mechanical energy is conserved, potential energy due to gravity will equal the kinetic energy of the used to throw the ball. This is represented by mgh=.5mv^2

1. Divide both sides of the equation by m to ignore mass. The new equation will be gh=.5v^2

2. Substitute values into the equation: 9.8h = (.5) (10^2) - - > 9.8h=50

3. Divide 50 by 9.8 to get h=5.102m
