Question

A 2 kg block is pushed 4.0 m along a horizontal floor by a force of magnitude 25 N at an angle θ=30.0° with the horizontal. The coefficient of kinetic friction between the block and the floor is 0.35. Calculate the magnitudes of (a) the work done by the applied force, (b) the work done by friction force, (c) the work done by the normal force, (d) the work done by gravity, (e) the change in kinetic energy of the block.
cos30^o =sin60^o=0.866 cos60^o =sin30^o=0.500 g=9.8 m/s²
