A ball falls from a tall bridge. The ball has a mass of 0.15 kg. The air density is 1.225 kg/m3

Question

. The ball’s surface area is 0.0026 m2
. The ball’s coefficient of drag is 0.007. What is the ball’s terminal velocity?

Answer 1

Terminal velocity = (2 * mass * gravity) / (air density * coefficient of drag * surface area)

Terminal velocity = (2 * 0.15 kg * 9.81 m/s2) / (1.225 kg/m3 * 0.007 * 0.0026 m2)

Terminal velocity = 11.7 m/s
