An object falling under the pull of gravity experiences a frictional force of air resistance. The magnitude of this force is approximately proportional to the speed of the object, f = bv. Assume b = 19 kg/s and m = 57 kg.
(a) What is the terminal speed that the object reaches while falling?
m/s
(b) Does your answer to part (a) depend on the initial speed of the object? Explain.
