A man pulls a crate of mass 51.0 kg across a level floor. He pulls with a force of 176.0 N at an angle of 30.0° above the horizontal. When the crate is moving, the frictional force between the floor and the crate has a magnitude of 114.0 N. 
If the crate starts from rest, how fast will it be moving after the man has pulled it a distance of 2.30 m?
