ii. If the body is released from this height, what will be its kinetic energy just before it hits the ground(g=10mlssquare2)?

or:... potential energy with respact to the ground.ii. If the body is released from this height, what will be its kinetic energy just before it hits the ground(g=10mlssquare2)?

or:E = mghConservation of energy.
