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.}

.
3. as grav force is acting perpendicular to the displ, so the work done by this force =0

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
