Question
An object falling under the pull of gravity is acted upon by a frictional force of air resistance. The magnitude of this force is approximately proportional to the speed of the object, which can be written as f = bv. Assume b = 19 kg/s and m = 59 kg.
What is the terminal speed the object reaches while falling?

at terminal speed, forcegravity=forcefriction
mg=19v solve for v.
mg=19v solve for v.
