A block of mass 1.8kg moves with a constant speed along a horizontal road.A force,F is applied at the block at an angle of 45(degrees) with the horizontal.The friction coefficient between the road and the block is given as 1/4....if the block is displaced by 2metres, find the work done (individually) by 1.force applied 2.friction 3.gravity {pls. explain the ans with diagram and the procedure.}
