. Let us consider a spherical rain drop, with diameter 4 mm, falling from 5.00 km until reaching the ground. a) Using that the air density is approximately 1.2 kg/m3 and the water density is 1.00 \times 103 kg/m3 what is work done by the air resistance? b) What is the total energy lost by the rain drop during its fall?
