During a workout, a football player ran up the stadium stairs in 45 seconds. The stairs  are 63m long and inclined at an angle of 27.5 (in other words, the hypotenuse of the  triangle is 63m). If a typical player has a mass of 85kg, estimate the average power  output on the way up. Ignore friction and air resistance.
