As shown in the figure, a 25 kg block is being pulled by a force F = 220 N up along a rough incline. The coefficient of kinetic friction between the block and the incline is μk = 0.30. The block is pulled through a distance of 23.0 m.
(c) Calculate the work (in Joules) done by the pulling force F. Pay attention to the angle in the work formula and the sign of work.
(d) Calculate the work (in Joules) done by the gravitational force. Pay attention to the angle in the work formula and the sign of work.
(e) Calculate the total work or network (in Joules).
(f) Apply the Work-Kinetic Energy Theorem: netWork=TotalWork=12mv2−12mv20=12m(v2−v20). The block starts from rest. What is its speed (in m/s)after being pulled through 23.0 m?
