Q10:

A block of mass m = 3.20 x 102 g is dragged with a string T across a rough horizontal table. The string tension is T = 2.95 N, and it pulls upward at an angle of d = 43.0 with the horizontal. At one particular instant, the block is moving at a speed of v = 6.70 m/s. The coefficient of kinetic friction between the block and the table is Mk = 0.669. m What is the power Pr supplied to the block by the string tension? 19.8 PT = W Incorrect What is the power Pr supplied by the force of friction? 10.3 Pf = W Incorrect
