A 1.5 kg ball is released from the rest from a height 0.409 m. This 1.5 kg ball then swings downward and strikes (fully elastic) a 4.60 kg ball that is at rest. a) Using the principle of conservation of energy, find the speed of the 1.50 kg ball at the height of 0.30 m. b) Find the maximum height of the 4.6 kg ball the collision c) Find the maximum velocity of 4.6 kg ball.
