A block of mass m = 3.20 102 g is dragged by a string across a rough horizontal table. The string tension is T = 2.63 N, and it pulls upward at an angle of = 48.0 with the horizontal. At one particular instant, the block is moving at a speed of v = 6.30 m/s. The coefficient of kinetic friction between the block and the table is k = 0.684. m What is the power PT supplied to the block by the string tension? What is the power Pf supplied by the force of friction? PT Pf= = = W W A block of mass m = 3.20 102 g is dragged by a string across a rough horizontal table.
