How much work is done when you push a crate horizontally with 120 NN across a 11-mm factory floor? Express your answer to two significant figures and include the appropriate units. WW = 1300 JJ If the force of friction on the crate is a steady 70 NN, find the KE gained by the crate. Express your answer to two significant figures and include the appropriate units.
