A) 25 kW
B) 10 kW
C) 5 kW
D) 2.5 kW

Solution :
As truck is moving on an incline plane therefore only component of weight \[(mg\sin \theta )\] will oppose the upward motion Power = force × velocity = \[mg\sin \theta \times v\] \[=30000\times 10\times \left( \frac{1}{100} \right)\times \frac{30\times 5}{18}=25\,kW\]
