2. Climbing a vertical rope is difficult. You must lift your full body weight with your arms. If your mass is 60 kg and you climb 2.0 m, by how much do you increase your gravitational potential energy? 3. A 1,500-gram object at 20 meters above the ground, free fall to the ground. What is the gravitational potential energy of the object?
