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.
