Terminal velocities of spheres.Calculate the approximate terminal velocities of a bowling (US) ball and a table-tennis (ping-pong) ball falling through air under the acceleration of gravity. The properties of the balls and air are summarized below. You may assume that gravity has an acceleration of 9.8 m/s2, that the air is stagnant, and that the drag over a sphere is well represented by the curves in this link from NASA.Properties of air at 20 C: ρ=1.2 kg/m3; k=0.026 W/m K; υ=15 x 10-6 m2/s.Bowling Ball: d=8.5 inches; m= 14 lb. The ball is smooth.Table Tennis Ball: m=2.7g; d = 40 mm. The ball is smooth.Which of the following pairs of numbers best represent the terminal velocities of the bowling ball and the tennis ball, respectively, in miles per hour?
