The force of air resistance on a raindrop is 5 x 10^-5 N when it falls with a terminal velocity of 4.2 m/s.
The acceleration of gravity is 9.8 m/s2.
What is the mass of the raindrop? Answer in units of kg.
How would I do this question? My understanding is to divide the Force of air resistance on a raindriop by the acceleration of gravity to get the mass of the raindrop.
and the other question is,
#2.

A block weighing 6.9 N requires a force of 2.4 N to push it along at constant velocity.
What is the coefficient of friction for the surface?
I'm new to friction so I don't know what to do here..
Any ideas would be appreciated. :)
