Question

If the power required to lift a weight of 10 N in 3 seconds is 60 W, what is the distance the weight moves? A. 1m B. 6m C.18m D.36m

Answer 1

we know that

Power = [work done]/[time taken]
work done=power*time taken
power---------- > 60 W
time taken------ > 3 sec
then
work done=60*3=180 J

and we know
work done=Force*distance
distance=[work done]/[force]
work done=180 J
force=10 N
distance=180/10=18 m

the answer is the option C.18m
