Question by xoxodcre16: A lawn roller is pushed across a lawn by a force of 118 N along the direction of the handle?
A lawn roller is pushed across a lawn by a force of 118 N along the direction of the handle, which is 22.5° above the horizontal. If you develop 65.2 W of power for 90.0 s, what distance is the roller pushed?

Best answer:

Answer by jj l
First find the force in the x direction
118Ncos(22.5)=
109.018N

Then plug into power equation (Work = Fd)

P = Work/t
P = Fd/t

65.2Watts = (109.018N)x/ 90.0s
x = 53.8m
