A spring with k=1600N/m is placed vertically on the floor. You drop a 1.20kg weight on it from a height of 0.800m. By how much will the spring be compressed?

Kinetic energy = 1/2mv^2. since the mass is constant we can form a ratio of it's kinetic energy at 60 divided by that at 30 to see ke(60)/ke(30) = +(60^2)/30^2). this may be said to 300% increase.
