Acompressed vertical spring stores 40 j of potential energy. the spring has a 0.1-kg stoneresting on it. the spring is released, throwing the stone straight up into the air. (a) how muchkinetic energy will the stone have when it first leaves the spring? (b) how much gravitationalenergy, relative to the spot where the stone was released, will the stone have when it reachesthe peak of its flight? (c) calculate the height above the release point to which the stone travels.(d) suggest something we could change about this situation that would cause the stone toreach a height double that calculated in part (c).
