A hawk of mass 10 kg dives to catch a mouse. During dive it loses 500 J of its potential energy. The height from where it begins its dive is (take g = 10 m/s2)

Change in Gravitational Potential Energy = mass x acceleration x change in height

500 J = 10 kg x 10 x change in height

Change in height = 5 m

So, the hawk dives to catch the mouse at a distance of 5m.
