011 (part 1 of 2) 10.0 points A 4.44 g object moving to the right at 23.4 cm/s makes an elastic head-on collision with an 8.88 g object that is initially at rest. 23.4 cm /s - - - - 4.44 g 8.88 g Find the velocity of the first object imme- diately after the collision. The acceleration of gravity is 9.8 m/s . Answer in units of cm/s. 012 (part 2 of 2) 10.0 points What fraction of the initial kinetic energy is transferred to the 8.88 g object
