Question

Sam "The Wall" Boney, famous goalie for the Milwaukee Polka Kings Hockey team, has played more like a sieve than a wall in recent games. Coach Matt Ashell sends Sam to the stadium steps to think about his less than stellar play.

A.) If Sam weighs 700 N and the stadium steps involve a vertical rise of 38 meters, how much work will he do in the 35 trips up the steps (neglect the trip down the stseps for this problem)?

B.) If Ashell requries Sam to complete this task in 7 minutes, what would be Sam's pwer output in Watts and in horsepower?

C.) Based on the information presented in lecture about hte relationship between the power output capabilities of the human body and activity duration, do you think that Sam will be able to satisfy Matt Ashell's request. Briefly explain.

Explanation / Answer

A) Workdone = N*m*g*h

= 35*700*38

= 931000 J

B) Power output = Workdone/time taken

= 931000/(7*60)

= 2216.7 Watts

c)
