A food shipper pushes a wood crate of cabbage heads (total mass m = 14 kg) across a concrete floor with a constant horizontal force F of magnitude 60 N. in a straight line displacement of magnitude d = 0.80 m, the speed of the crate decreases from vo = 0.80 m/s to v 0.30 m/s. (a) How much work is done by force F (b) What is the increase AEn in the thermal energy of the crate and floor?
