Question

A 6.0-kg block is pushed 8.0 m up a rough 37° inclined plane by a horizontal force of 75 N. If the initial speed of the block is 2.2 m/s up the plane and a constant kinetic friction force of 25 N opposes the motion, calculate (a) the initial kinetic energy of the block; (b) the work done by the 75-N force; (c) the work done by the friction force; (d) the work done by gravity; (e) the work done by the normal force; (f) the final’ kinetic energy of the block.
