Thanks, I got the position x where the velocity is greatest, but I still can't get the mac velocity. I tried putting that x value in the spring potential energy equation and setting that equal to the kinetic energy and solving for v, but it said the velocity I got was wrong. This question is...
Homework Statement
The spring of a spring gun has force constant k = 400 and negligible mass. The spring is compressed 6.00 and a ball with mass 0.0300 is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of...
