If a mass were hung from a spring and the extension was measured to be "x", and then the same mass was hung from two identical springs side by side (in parallel), how far would the mass extend the pair of springs? 0.25 x 0.5x Ox O 2x None of these answers is correct When a baseball bounces on the ground the force applied by the surface is smaller than if it didn't bounce kinetic energy is imparted to the ground momentum is conserved in the Earth-ball system the impulse is the same as if the ball landed without bouncing it leaves the surface with the same speed that it impacted the surface with
