Here- kinetic energy of the body- K-E-10-xA0-JEk-10JHeight attained by the body- h-5-xA0-mh-5mWhen the body attains maximum height- its kinetic energy is converted into potential energy-P-E-K-E-x27F9-mgh-10-x27F9-m-10gh-1010-xD7-5-0-2-xA0-kg

A body is thrown up with a kinetic energy of 10J. If it attains a maximum height of 5m, find the mass of the body.

Here, kinetic energy of the body, $K . E = 10 J$
Height attained by the body, $h = 5 m$

When the body attains maximum height, its kinetic energy is converted into potential energy.

$P . E = K . E$

$⟹ m g h = 10$

$⟹ m = \frac{10}{g h} = \frac{10}{10 \times 5} = 0.2 k g$
