James being a good samaritan decided to help his neighbor get his cat on the tree 4.61 m high. He then uses a ladder to get the cat. How much work does James need to do to rescue the cat if he has a mass of 87.3 kg?

Step 1
The formula for gravitational potential energy is: PE = m * g * h where m is the mass of James (87.3 kg), g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height of the tree (4.61 m). PE = 87.3 kg * 9.81 m/s² * 4.61 m PE = 3927.0973 Show more…
