Question: Now the friends decide to try a problem. A metal ball of mass 0.5 kg is dropped from a great height, so that it reaches terminal velocity before hitting the ground. Its terminal velocity is measured to be 41 m/s.
Part A: What is the radius of the ball?
Please show all work and steps to find the radius of the ball, use 1.2 kg/m3 for the density of air, and 0.5 for D.
