Work Energy And Power Question 193

Question: A truck of mass 30,000kg moves up an inclined plane of slope 1 in 100 at a speed of 30 kmph. The power of the truck is (given $g = 10 m s^{- 1})$ [Kerala (Engg.) 2001]

Options:

A) 25 kW

B) 10 kW

C) 5 kW

D) 2.5 kW

Show Answer

Answer:

Correct Answer: A

Solution:

As truck is moving on an incline plane therefore only component of weight $(m g \sin θ)$ will oppose the upward motion Power = force × velocity = $m g \sin θ \times v$

$= 30000 \times 10 \times (\frac{1}{100}) \times \frac{30 \times 5}{18} = 25 k W$
