Question

A 95 kilogram student climbs 4.0 meters up a rope in 3.0 seconds. what is the power output of the student?
a. 1.3 x 10^2 w

Answer 1

Mass of student m = 95kg
 Length of tye rope L = 4 m
 Time taken t = 3 sec
 Power = Work / t
  Work = m x g x h = 95 x 4 x 9.81 = 3727.8
 Power = 3727.8 / 3 = 1.2 x 10^3 Watts
