Question

) A crate is hauled 8m up a ramp under a force of 200N applied at an angle if 250
to
the ramp. Find the work done

Answer 1

25 degrees to ramp?
ramp length = 8 m or 8 m up? assume length = 8 m
then work = distance moved * force in direction of motion
= 8 * 200 cos 25 = 1600 cos 25 Joules
