How much potential energy does Tim, with mass 64.0 kg, gain when he climbs a gymnasium rope a distance of 3.3 m?

In an effort to impress Mr. Hass during PE class, Avery quickly elevates his 62.6-kg body up the rope to a height of 5.69 meters above his starting point. What is Avery's change in potential energy?

While riding a chairlift, a 58 kg skier is raised a vertical distance of 366 m.  By how many joules will the skier's gravitational potential energy increase when she reaches the top of the lift?

Don (82.8 kg) is going bungee jumping. The bridge he will jump off of is 54.0 m above the ground. After Don jumps, he comes to a spot 10.3 m above the ground before the bungee pulls him back.How much elastic energy is in the bungee cord when Don is 10.3 meters above the ground? If 6,200 J of the elastic energy (use your number from above) is converted to internal energy, to what height will Don return when the bungee bounces him back up? If Don drops his phone (0.18 kg) when he is 28.4 m in the air, what speed will it reach before it hits the ground?

A man of mass 60 kg steps onto a podium of height 30 cm. What is the gravitational potential energy gained by the man? [g = 10 N/kg]

A weight lifter raises a 180 kg barbell to a height of 1.95 m. What is the increase in the potential energy of the barbell?
