Question:
A block of mass=315g is dragged with a string across a rough horizontal table. The string tension is=2.97,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=6.98 m/s.The coefficient of kinetic friction between the block and the table isk=0.624.
What is the power supplied to the block by the string tension?
T=
