The frictional force on the crate is 28 N. How much work is done on the crate by the friction force, in Joule? Use g = 10,0 m/s2 Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
