Determine the power supplied by the force of friction

Reference no: EM13273422

A block of mass m = 364 g is dragged with a string across a rough horizontal table. The string tension is T = 2.79 N, and it pulls upward at an angle of Ï? = 49.0Â° with the horizontal. At one particular instant the block is moving at a speed of v = 6.5 m/s. The coefficient of kinetic friction between the block and the table is Î¼k = 0.669.

What is the power supplied to the block by the string tension?

What is the power supplied by the force of friction?
