A pendulum bob with mass of 3.0 kg is suspended from an ideal string a distance of 3.5 m from the ceiling. A 0.004 kg bullet is fired horizontally at a speed of 6.91x103 m/s and imbeds itself in the bob. Determine the angle through which the bob swings when it comes to rest, the maximum acceleration of the bob when its speed is zero, and the amount of time it takes for the bob to come to rest for the first time after the collision.?
