Question

Derive an expression for work done in sliding body down a rough inclined plane.

Open in App

Solution

friction force, $f = μ R = μ m g c o s θ$

$μ$ is the coefficient of the friction.

Net force in forward direction, $F = m g s i n θ - μ m g c o s θ$

Let the distance travelled by the body is , $S$ .

work done, $W = F . S$

$W = (m g s i n θ - μ m g c o s θ) . S$
