Problem 5.33 (Multistep) In the dark in outer space, you observe a glowing ball of known mass 4.6 kg moving in the plane at constant speed in a circle of radius 7.5 m, with the center of the circle at the origin (<0, 0, 0> m). You can't see what's making it move in a circle. At time 0 the ball is at location <7.5, 0, 0> m and has velocity <0, -80, 0> m/s.
