Question

Spherical steel ball of diameter 40 mm and of density 8500 kg/m3 is dropped in large mass of water. The co-efficient of drag of the ball in water is given as 0.45. Find the terminal velocity of the ball in water. If the ball is dropped in air, find the increase in terminal velocity of ball. Take the density of air =1.25 kg/m3 and cd =0.1
