A raindrop with a radius of 1.5 mm falls from a cloud that is at a height of 1200 m above the ground. The drag coefficient (C) for the drop is 0.60. Assume that the drop is spherical throughout its fall. The density of water is 1000 kgm^-3 and the density of air is 1.2 kgm^-3. Then the terminal speed of the drop is (g = 9.8 ms^-2)
