A 00380 kg ball is shot from the plunger of a pinball machine. Because of a centripetal force of 0.0287 N, the ball follows a circular arc whose radius is 0.423 m. What is the speed of the ball? Number l Units v A satellite is in a circular orbit around an unknown planet. The satellite has a speed of 1.02 x 104 m/s, and the radius of the orbit is 4.17 x 10'5 m. A second satellite also has a circular orbit around this same planet. The orbit of this second satellite has a radius of 6.77 x 106 m. What is the orbital speed of the second satellite? Number Units V
