Question:
A block of mass =309 g is dragged with a string across a rough horizontal table. The string tension is =2.47 N, and it pulls upward at an angle of =46.0 with the horizontal. At one particular instant, the block is moving at a speed of =6.90 m/s. The coefficient of kinetic friction between the block and the table is k=0.624.
What is the power f supplied by the force offriction?
