Question

An engine develops 20 &#160; kW of power. How much time will it take to lift a mass of 200 &#160; kg to a height of 40 &#160; m ? &#160; g = 10 &#160; m &#160; s - 2

Aicharya · Accepted Answer

In physics, power is the amount of energy transferred or converted per unit time.

Power, $P = \frac{m \times g \times h}{t}$

$\Rightarrow t = \frac{m \times g \times h}{P}$

$\Rightarrow t = \frac{200 \times 10 \times 40}{20000}$

$\Rightarrow t = \frac{80000}{20000}$

$\Rightarrow t = 4 s$
