Consider a 4-mg raindrop that falls from a cloud at a height of 2 km. when the raindrop reaches the ground, it won't kill you or even bruise you because its terminal velocity is just 10 m/s. calculate the work done by the air resistance on the raindrop over the course of its fall to the ground. make sure you report your answer with the correct sign. again, assume that the falling raindrop maintains its shape so that no energy is lost to the deformation of the droplet
