A raindrop of mass 1.06 × 10−5 kg falls in air

and reaches a terminal speed of 4 m/s.

The acceleration of gravity is 9.8 m/s2 .

What is the value of the constant k that

determines the resistive force F = k v ?

Answer in units of kg/s

Part B)

If there were no air resistance, how long would

it take the raindrop to reach the same speed?

Answer in units of s.

I'm sorry there's no work, but I just have no idea where to start. We haven't even learned about air resistance in my class yet, and I was assigned this for homework.
