Question

Peter weighs 100 pounds. He ran up a 6 foot hill in 2 seconds. What was Peter's power output?

A. 1,200 ft-lbs./sec
B. 600 ft-lbs./sec
C. 300 ft-lbs./sec
D. 100 ft-lb/sec

Answer 1

Answer option C: 300ft-lbs/sec is your answer

Answer 2

300lb-ft/secs

Step-by-step explanation:

Given parameters:

Weight of Peter = 100lb

Height of hill = 6ft

Time taken = 2s

Unknown:

Power output of Peter = ?

Solution:

Power is the rate at which work is being done. It is expressed as;

Power =
`(Work done )/(time taken)`

Work done = force x distance = weight x height = 100lb x 6ft

Work done = 600lb-ft

Power =
`(600)/(2)` = 300lb-ft/secs
