Work is defined as force applied multiplied by the HORIZONTAL distance traveled. The force applied is parallel to the ramp so we must take the distance that is parallel to the ramp.

I put it in caps because the problem says it was raised a vertical distance.

The Horizontal distance it traveled is ( 1.15 m ) x Sin 30, and is definitely , 0.575

therefore,

#W= 225N * 0.575 m#

W = 129.375 N-m

1 N-m is 1 J ( joule)

W= 129.375 J
