A man of mass 50 kg jumps to a height of 1 m. His potential energy at the highest point is$(g=10\ m/s^2)$:- 50 J
- 500 J
- 5 J
- 5000 J
Here mass of the man $m=50\ kg$
Height $h=1\ m$
Gravitational acceleration $g=10\ m/s^2$
Therefore, potential energy at the highest point $=mgh$
$=50\times1\times10$
$=500\ J$
Therefore, option b). is correct.
