Question

An object falling under the pull of gravity is acted upon by africtional force of air resistance. The magnitude of this force isapproximately proportional to the speed of the object, which can bewritten as f = bv. Assume that b =16 kg/s and m = 44 kg. (a) What is the terminal speed that the objectreaches while falling?
Enter anumber. 1 m/s
(b) Does your answer to part (a) depend on the initial speed of theobject? 2 Yes No   

A= -9.8m/s^2
How should I attempt the problem?
What is the formula for calculating terminal speed?
Enter anumber. 2

Explanation / Answer

Terminal speed F = b v                      mg = b v       mass of the object is m = 44 kg , b = 16 kg / s = 16*10-3 m/s                   v   = m g / b                       = 44 * 9.81 / 16.*10-3 m/s                      = 26.9*103 m/s          b ) No
