The power of a crane, which lifts a mass of $1000$ kg to a height of $20$ m in $10$ s is :
( $g = 9.8$ m/s $^{2}$ )NEET 2026 (Cancelled)

Options:

Answer:

Solution:

Given $m = 1000$ kg, $h = 20$ m, $t = 10$ s, $g = 9.8$ m/s $^{2}$ .

Work done by the crane is $W = m g h$ .

$W = 1000 \times 9.8 \times 20 = 196000$ J.

Power is the rate of doing work, $P = \frac{W}{t}$ .

$P = \frac{196000}{10} = 19600$ W.

$P = 19.6$ kW.

Answer: $19.6$ kW
