A body of mass 2 kg is dropped from a height of 200 m Find t

A body of mass 2 kg is dropped from a height of 200 m. Find the limiting velocity of the body if it encounters a resistance force equal to 50v.

Solution

Downward gravity force is, 2g and air resistance is:-50v

Limiting velocity is when gravity force is balanced by air resistance

So, 2g=50v

v=2g/50=2*9.81/50=0.39 m/s
