A ball of mass 0.470 kgkg moving east (+x+xdirection) with a speed of 3.84 m/sm/s collides head-on with a 0.235 kgkg ball at rest. Assume that the collision is perfectly elastic. 1.What is be the speed of the 0.470-kgkg ball after the collision? Express your answer to three significant figures and include the appropriate units. 2. What is be the direction of the velocity of the 0.470-kgkg ball after the collision? East or west? 3.What is the speed of the 0.235-kgkg ball after the collision? Express your answer to three significant figures and include the appropriate units. 4.What is the direction of the velocity of 0.235-kgkg ball after the collision? East or west?
