If the kinetic energy of a 0.62kg stone is 2.3J at its highest point and 9.4J at its lowest point how do I calculate the height at the highest point.

Gravitational potential energy is mgh.
Kinetic energy is 1/2 mv^2 (although you don't need that)
So the difference in energy turns to gravitational potential. Solve delta E=mgh for h. Easy enough?

The stone is flying in a parabolic arc.
At the highest point, it has a horizontal kinetic energy only.
At the lowest point, the additional kinetic energy is due to the drop
m*g*d=9.4-2.3
d=(9.4-2.3)/(9.81*.62)
d=1.17m
