A man pulls a crate of mass 53.0 kg across a level floor. He pulls with a force of 180.0 N at an angle of 28.0 above the horizontal. When the crate is moving, the frictional force between the floor and the crate has a magnitude of 124.0 N.
If the crate starts from rest, how fast will it be moving after the man has pulled it a distance of 2.70 m?
