Question

1. A body is pulled along a rough horizontal plane through a distance of 5 m by applying a constant forceof 4N. Find the work done by the force when (i) the force is applied along the plane and (ii) the force isapplied at an angle of 60° with the plane.

Answer 1

Explanation:

A body of mass 40 kg is dragged 8 meter on a rough horizontal surface in 10 with a constant velocity by a constant force of 20 N, then calculate the work done by the force and total work done by all the forces.
