Given

Point A

U: gravitational potential energy

U = 480 J

Point C

U = 290 J

Procedure

Assuming that there are no non-conservative forces in the system, such as friction. The energy must be conserved at each point distributed between gravitational and kinetic potential.

Therefore, at point C kinetic ernegy would be 190 J
