Question

A Raindrop of mass 1 g falling from a height h of 1 km hits the ground with a speed of 50 m/s calculate - The loss of potential energy of drop . ?

Answer 1

Heya......!!!

According to the problem , the mass of raindrop ( m ) = 1 g => 1×10^-3 Kg
Height ( h ) = 1 Km => 1000m and g = 10m/s^2
Speed of drop ( v ) = 50m/s .

Loss of potential energy of the drop =>> mgh

»»» 10^-3 × 10 × 10^-3 =>> 10 J

Loss of potential energy of Raindrop ➡ 10 J.
