Atoy cork gun contains a spring whose spring constant is 10.0n/m. the spring is compressed 5.00cm and then used to propel a 6.00-g cork. the cork, however, sticks to the spring for 1.00cm beyond its unstretched length before separation occurs. the muzzle velocity of this cork is: a. 1.02m/s
b. 1.41m/s
c. 2.00m/s
d. 2.04m/s
e. 4.00m/s
