How much energy has been lost to friction


A 250 kg block is pulled from rest along a rough surface by rope inclined 25 degree to horizontal. the tension in the rope is 650 N. The friction force is 89 N. Determine the acceleration of the block, the velocity of the block after 6 seconds, and the kinetic energy of the block. after the block slides 2 m, how much energy has been lost to friction.
