15 Work is done when a force of 400N pulls a crate of weight 500N at a constant speed along a ramp, as shown. 5.0 m 400 N 3.0 m 500 N Part of the work done increases the gravitational potential energy E of the crate and the rest is work done W against friction. What are the values of E and W? E/J W/J A 1500 500 B 1500 2000 C 2000 2500 D 3500 500
