Simple Spring Problem Help!! A spring gun fires an object of mass 2.1 kg horizontally across a frictionless table. The spring has a spring constant of 19 N/m and is initially compressed by 3.6 cm. What is the speed of the object as it leaves the spring gun? I can not figure out this problem. 3.6cm = 0.036 m then I tired (0.036)(19) then dividing that by the mass nothing seems to be working Any help or direction would be great! Thank you!
