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 = 15 kg/s and m =
50 kg. (a) What is the terminal speed the object reaches while
falling? (b) Does your answer to part (a) depend on the initial
speed of the object? Explain.
