# A body weighing 50 kg was evenly lifted along an inclined plane 1 meter high, while the work expended

A body weighing 50 kg was evenly lifted along an inclined plane 1 meter high, while the work expended was 700 joules. The efficiency of the inclined plane is …

Data: h (height of the taken inclined plane) = 1 m; m (mass of the body lifted using the plane) = 50 kg; Az (work expended) = 700 J.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

To determine the efficiency of the taken inclined plane, we apply the formula: η = Ap / Az = m * g * h / Az.

Calculation: η = 50 * 10 * 1/700 = 500/700 = 0.714 or 71.4%.

Answer: The efficiency of the taken inclined plane is 71.4%.
