A 1kg ball is hitting the ground with 850 Joules of kinetic energy. How high will it bounce?

The ball has 850J of kinetic energy, thus it converts all this energy into potential energy when boucing back. The potential energy at height h is mgh (m is the mass, here 1kg, g the gravitational acceleration) and solve
mgh=850J
with problem's data.
