Students were instructed to watch this ahead of class.
Do Now
A Bullet of mass 0.100 kg is pressed against the spring of a gun. The spring stiffness k = 250 N/m. is compressed 6 cm and released. If the bullet detaches from the spring when the spring reaches its neutral height (X=0). Find the velocity of the bullet?
Do Now Part 2
A spring of k=600 N/m is compressed .1m by .05kg box. After it launches vertically, find the speed of the box as soon as it leaves the spring and the max height. Good luck.
