rol Q A 5. A clay ball with mass m has speed ve as it approaches a clay ball with mass 3m. The 3m ball is initially at rest and hanging from a string with unknown length L. See figure. Then, the two balls have an inelastic collision, so that they stick together. After colliding, both balls move upward along a circular path, reaching a maximum height, max, at angle y. Find y. If the magnitude of the tension force in the string immediately 16 after the collision is 7-mg, what is L? The knowns are m, g, and vo. (20 points) 3 center of circle gravity direction. string, L=? ²1. Ww? 3m at rest before collision. hax?
