Q14MEnergy, Work and PowerFree sample

A block is pulled along a horizontal floor by a horizontal rope. The tension in the rope is 500 N500\text{ N} and the block moves at a constant speed of 2.75 m s12.75\text{ m s}^{-1}. Find the work done by the tension in 40 s40\text{ s} and find the power applied by the tension.
