1. The problem statement, all variables and given/known data A cork gun contains a spring whose spring constant is 10 N/m. The spring constant is compressed 5 cm and then used to propel a 6 gram cork. The cork, however, sticks to the spring for 1 cm beyond its unstretched length before separation occurs. What is the muzzle velocity of this cork? (in m/s) 2. Relevant equations Kf - Ki = -1/2kd2 3. The attempt at a solution -1/2mv2 = -1/2kd2 v = d*(k/m)1/2 v = 5/100m*(10/(6/1000))1/2 v = 2.04 m/s Not sure I did that right though cuz the part where the cork sticks to the spring for 1 cm throws me off. Could someone help me out?
