A block of mass 5kg start at point A with a speed of 15m/s on flat frictionless surface. At point B, it encounters an incline with coefficient of kinetic friction 0.5. The block makes it up the incline to a second flat frictionless surface. What is the work done? what is the velocity of the block at point C. The incline is 2.2m long at an angle of 15.
