A pendulum consists of a ball of mass 3.0 kg on a string of length 4.0 m. The ball is pulled back untilits center has risen to a height of 0.80 m. The ball is released such that it strikes a 1.0 kg block at thebottom of its swing. The block comes to a rest after traveling 2.0 m across a surface withμk= 0.15.What is the speed of the ball right after the collision? Is the collision elastic?
