## Homework Statement

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?

## Homework Equations

## The Attempt at a Solution

a. Fg=-mgj=(3.07X10^-5)(-9.8m/s^2j)

=-3.0086x10^-4

delta r=???

w=????

Could someone please tell me if this is correct so far and help me find delta r?

Thank you very much
