The PE and KE are given in some places in the diagram below. Fill in the rest.

Using the conservation of energy:
For PEg = 7500J
KE = 10000J - 7500J = 2500J
------------------------------------
For PEg = 2500J
KE = 10000J - 2500J = 7500J
------------------------------------
For PEg = 0J
KE = 10000J - OJ = 10000J
