Problem 4 You drop a (1.5 kg ball from a height of 2 rn. and it bounces back to a height of 1.5m. Consider the system formed by the ball and the Earth, so we can speak properly of its graintatiornl potential energy. (a) What is the kinetic energy of the ball just before it hits the ground7 (b) What is the kinetic energy of the ball just atter it bounca up? (c) What is the coeflicient of restitution for this collision? (d) What kind of collision is this (elastic. inelastic, etc )? Why? {e} lfthe coefficient of ratitution does not change. how high would the ball rise on a second bounce? (f) On the graphs below. draw the energy bar diagrams For the system. (I) as the ball leaves your hand. (2) just before it hits the ground [assume fr (l for practical purposes]; [3) Just after it leaves the ground on its wayr up (I! [i still]. and (4] at the top of its (first) bounce. Malia sure to do this to scale, consistent with the values for the energies you have calculated above.
