2. A block of mass m= 3 kg is released from rest at the top of a rough incline surface (0 = 30°), as shown. It reaches the bottom of the incline with a speed of 15 m/s. (a) Calculate the work done by the frictional force. [2 points) (b) Calculate the coefficient of friction between the block and the incline surface. 3 points] 20.0 m
