- A block of mass m = 331 g is dragged by a string across a rough horizontal table. The string tension is T = 3.11 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 = 6.50 m/s. The coefficient of kinetic friction between the block and the table is = 0.654. What is the power PT supplied to the block by the string tension? What is the power Pf supplied by the force of friction? At this instant, the block's speed is increasing. impossible to determine. constant. decreasing. m PT = W W P =
