In the figure below a ball of mass 5 kg starts at point A with a speed of 15 m s on a flat frictionless surface After point B it trav els on an incline BC with coefficient of kinetic friction 0 15 At point B the ball smoothly changes the direction The length of the incline is 2 2 m and it makes an angle of 15 with the horizontal What is the work done by friction What is the velocity of the ball at point C Given Sin 15 0 25 Cos 15 0 95 A B 8
