Decide the spring constant

Reference no: EM13673976

A rifle fires a 1.26 x 10^-2-kg pellet straight upward, as 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 7.92 x 10^-2 m from its unstrained length. The pellet rises to a maximum height of 6.12 m above its position on the compressed spring. Ignoring air resistance, decide the spring constant.
