A man of mass 50 kg jumps to a height of 1 m. His potential energy at the highest point is$(g=10\ m/s^2)$:

1. 50 J
2. 500 J
3. 5 J
4. 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.
