5054Work
Work is done when a force of 400 N pulls a crate of weight 500 N at a constant speed along a ramp, as shown. 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?
- AE = 1500 J, W = 500 J
- BE = 1500 J, W = 2000 J
- CE = 2000 J, W = 2500 J
- DE = 3500 J, W = 500 J
