User the figure shows a horizontal frictionless surface, two immovable walls, two springs, and two masses. You are going to perform an experiment in which you compress each spring as shown and then release the masses from rest. when the springs reach their equilibrium position, the masses lose contact with the springs, and the masses head toward each other on a collision course.what principle of physics will you use to find the speed of each mass just after it loses contact with its spring? derive an equation for the speed of the block of mass m just after it loses contact with its spring
