Arifle fires a 3.56 x 10-2-kg pellet straight upward, because the pellet rests on a compressed spring that is released when the trigger is pulled. the spring has a negligible mass and is compressed by 6.61 x 10-2 m from its unstrained length. the pellet rises to a maximum height of 4.83 m above its position on the compressed spring. ignoring air resistance, determine the spring constant.
