Question: A 0.050-kg dart is fired vertically from a spring gun that has a spring constant of 4000 N/m. Prior to release, the spring was compressed

A 0.050-kg dart is fired vertically from a spring gun that has a spring constant of 4000 N/m. Prior to release, the spring was compressed by 10.7 cm. When the dart is 6.8 m above the gun, its upward speed is 28 m/s. Determine the maxi mum height reached by the dart.
