A block of mass 2.0 kg is pushed down an inclined plane of inclination $37^{\circ}$ with a force of 20 N acting parallel to the incline. It is found that the block moves on the incline with an acceleration of $10 m / s^{2}$ . If the block started from rest, find the work done $(W_{F})$ by the applied force, work done $(W_{g})$ by the weight of the block and work done $(W_{f})$ by the frictional force acting on the block in the 1st second. Take $g = 10 m / s^{2}$ .
