A truck of mass 30,000 kg moves up an inclined plane of slope 1 in 100 at a speed of 30 kmph. The power (kW)of the truck is (given  g=10ms−2)

As truck is moving on an incline plane therefore only component of weight  (mgsinθ) will oppose the upward motion Power = force × velocity =  mg sinθ×v=30000×10×1100×30×518=25 kW
