Question

Example 11 A block of mass mat is to be slowly slid
through a distance d on the rough horizontal surface of the
friction coefficient u by applying a force at angle ou with
horizontal. Find the work done by the force if the applied
force is minimum​

Answer 1

Explanation:

Let the force applied on the block be F ,The surface applies a frictional force on the block in the backward direction.Vertical direction : N + Fsinθ ...
