A raindrop of mass 3.07 X 10^-5 kg falls vertically at constant speed under the influence of gravity and air resistance. Model the drop as a particle.
a. As it falls 50m, what is the work done on the raindrop by the gravitational force?
b. What is the work done on the raindrop by air resistance?
The Attempt at a Solution
Could someone please tell me if this is correct so far and help me find delta r?
Thank you very much
