Two physicists, both of mass 50 Kg climb up identical ropes suspended from the ceiling of a gymnassium. The ropes are 15 m long. Physicist 1 reaches the top twice as quickly as physicist 2 does. After physicist 2 also reaches the top, they argu about who did more work against gravity. Physicist 1: I did more work against gravity, because I was over coming gravity more quickly. your climb was lazier, and therefore, you did less work. Physicist 2: No was, I did more work against gravity because I spend more time climbing the rope. Answer the following questions: Physicist-1 climbed his rope in 30 sec. What average power did he exert against gravity (g=10m//s^(2))
