Question

Calculate the work done to move a body of mass $10$ kg along a smooth inclined plane with constant velocity through a distance of $10$ m.

Open in App

Solution

$W = F d = m g s i n θ d$
$G i v e n d = 10 m, m = 10 k g, θ = 30^{0}, g = 10 m / s e c^{2}$
$W = 10 \times 10 \times s i n 30 \times 10$
$= 500 J$
