A crane pulls up a car weighing $500\ kg$ to a vertical height of $4\ m$. Calculate the work done by the crane.

Academic Physics NCERT Class 9

Here given: Mass of the car $m=500\ kg$

Vertical Height $h=4\ m$

Therefore, work done $W=mgh$

$=500\times9.8\times4$

$=19,600\ Joule$

Thus, the work done by the crane is $19,600\ Joule$.
