Question

Felix expends 100 W of power to climb 10 meters in 20 seconds. How much force does he exert?
\l "\l " A. 400 N

\l "\l " B. 20 N

\l "\l " C. 200 N

\l "\l " D. 10 N

Answer 1

Power = work / time

 

Work = 100 × 20 = 2000

 

Next we use the equation

 

W = Force × distance

 

2000 J = F × 10

 

F = 200 N

 

C is your answer
