A winch drags a 200 kg crate along a 15 degrees incline at 0.2 m/s. The coefficient of kinetic friction is 0.22.

What is the power required as the crate moves up the slope?

1 answer

F = m g sin 15 + .22 m g cos 15

power = force * speed

= (m g sin 15 + .22 m g cos 15).2
in Joules/second or Watts
