A toy gun uses a spring of very large value of force constant k. When charged before triggering in the upward direction, the spring is compressed by a small distance x. If mass of shot is m, on being triggered it will go up to a height of:
- \(\frac{k x^{2}}{m g}\)
- \(\frac{x^{2}}{k m g}\)
- \(\frac{k x^{2}}{2 m g}\)
- \(\frac{(K x)^{2}}{m g}\)
Answer
(C) k x^ 2 2 m g
