1. The problem statement, all variables and given/known data There is a box that is 4m above a spring on a ramp at a 30° angle. box is 10kg. we let the box go and it collides with a spring, that has a k of 250N/m At what compression of the spring does the box have its maximum speed. 3. The attempt at a solution ok I found the max compression of the spring. Im not sure how to find the max speed of the box. Could I just right the speed of the box as a function of spring compression and height and take its derivative and maximize that?
