Question

A raindrop of mass 3.35X10^-5 falls vertically at a constant speed under the influence of gravity and air resistance.  Model the drop as a particle.  As it falls 100 m, what  is the work done on the raindrop (a)by the gravitational force and
(b) by air resistance

So I figured that W=F delta r
= mass * acceleration * delta r
So I figured how to do (a)

I need help on finding out the work done on the particle by air resistance.  How do I do that?

anonymous · Answer

take a=9.8 as acceleration due to gravity

how do I find the air resistance though?  I feel as if the question is out of the blue since I'm not given any info on it.
