A crate slides down a ramp that makes a 20o angle with the ground. To keep the crate moving at a steady speed, Paige pushes back
on it with a 68 N horizontal force. How much work does Paige do on the crate at is slides 3.5 m down the ramp?
1 answer:
Answer:
-223.64684 J
Explanation:
F = Force that is applied to the crate = 68 N
s = Displacement of the crate = 3.5 m
= Angle between the force and displacement vector = (180-20)
Work done is given by

The work that Paige does on the crate is -223.64684 J
