Need very fast answer within 5 minutes I needed answer

A box of mass m is pressed against (but is not attached to) an ideal spring of force constant k and negligible mass, compressing the spring a distance x. After it is released, the box slides up a frictionless incline as shown in the figure and eventually stops. If we repeat this experiment with a box of mass 2m k Smooth 0000000- Smooth both boxes will reach the same maximum height on the incline. A box and a spring on a smooth surface, the lighter box will go twice as high up the incline as the heavier box. O both boxes will have the same speed just as they move free of the spring. just as it moves free of the spring, the lighter box will be moving twice as fast as the heavier box. just as it moves free of the spring, the heavier box will have twice as much kinetic energy as the lighter box
