An angry rhino with a mass of 2200 kg charges directly toward you with a speed of 4.40 m/s. Before you start running, as a distraction, you throw a 0.180 kg rubber ball directly at the rhino with a speed of 7.46 m/s. Determine the speed of the ball (in m/s) after it bounces back elastically toward you. 7179.33 X After establishing that energy and momentum are conserved, see if you can write a statement of conservation of momentum and a statement of conservation of energy. Each of these two statements will contain the two unknowns (final speed of the rhino and ball) and may be solved simultaneously to obtain an expression which will allow us to determine the final speed of the ball. m/s Additional Materials
