During a workout, the football players at State U. ran up the stadium stairs in 61 s. The stairs are 145 m long and inclined at an angle of 30°. If a typical player has a mass of 105 kg, estimate the average power output on the way up. Ignore friction and air resistance.

power=work/time=145sin30*105g/61 watts

This was one of my labs, the lard butts in physics got some exercise and some calculations.
