Expert Answer

Step 1

The change in gravitational potential energy depends on the difference between the initial and final height of the heroin. The gain in gravitational potential energy acquired during the jump to to the top of the building will be lost during her dive to the bottom of the excavation. The equation for the gravitational potential energy is given by
