J (b) Determine the increase in internal energy of the crate-incline system owing to friction. J (c) How much work is done by the 98−N force on the crate? J (d) What is the change in kinetic energy of the crate? J (e) What is the speed of the crate after being pulled 4.98 m? m/s

Stick Guy pulls a 18−kg crate of stuff across a rough floor with a constant applied force, Fapp = 39.6 N, accelerating it from rest to a speed of 3.4 m/s over a distance of 4.6 m. (a) What was the change in the crate's KE, PE, and ME? ΔKE = J ΔPE = J ΔME = J (b) How much work was done on the crate? Wnet = J (c) How much work was done on the crate by non-conservative forces? Wnc = J (d) How much work did Stick Guy do on the crate? Wapp = J (e) What can you conclude about the work done by friction? Wf = J (f) The magnitude of the frictional force acting on the crate is therefore: f = m = N
