What is the power supplied by the force of friction

Reference no: EM13243120

A block of mass m = 331 g is dragged with a string across a rough horizontal table. The string tension is T = 3.27 N, and it pulls upward at an angle of ? = 42.0° with the horizontal. At one particular instant the block is moving at a speed of v = 6.9 m/s. The coefficient of kinetic friction between the block and the table is ?k = 0.579.
