A Ping-Pong ball has a mass of 2.3 g and a terminal speed of 9.3 m/s. The drag force is of the form bv2 What is the value of b?

The equation of the forces action on a falling body with viscous slowing force proportional to the velocity squared is \[Net ~ force =mg-bv ^{2}\] Since the net force is zero when the object reaches terminal velocity solve the above equation for b.
