A fireman of mass 80 kg slides down a pole.

A fireman of 80 kg slides down a-pole. As he achieves the
base, 4.2 m below their starting place, their rate is 2.2 m/s. By
exactly how much features thermal power increased during their fall?

Mass, m= 80kg
Preliminary level of fireman, H= 4.2m
Preliminary complete power= Possible power just

At base, velocity, v= 2.2m/s
Complete Energy at bottom= Kinetic Energy just
hence,
Difference b/w energies will launch as thermal power,
Therefore Thermal Energy,
