"During workout, the football players at (insert generic college here) ran up the stadium stairs in 66 seconds. The stairs are 140m long and inclined at an angle of 32 degrees. If a typical player has a mass of 95 kg, estimate the average power output on the way up. Ignore friction and air resistance."
w= Fd p= w/t maybe law of sin/cos perhaps p=Fv might be useful, i doubt it change in energy/time=power
The Attempt at a Solution
use law of sines to calculate that the change in height in roughly 87 meters.
Change in energy/time=power= ( 95kg*87m*10m/s^2)/(66s)=1,252 W
The correct answer was 1,000 W, and I am very frustrated. This is one of the few questions in the chapter I cannot answer. Please help, feedback appreicated
