Q1
A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by the friction force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 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.
