**A 0.252-kg block is dropped straight downwards onto a vertical spring. The spring constant of the spring is 57 N/m. The block sticks to the spring and the spring compresses 0.13 m before coming to a momentary halt. What is the speed of the block just before it hits the spring?**

well the restoring force F is equal to -kx. I need to find out how many seconds the block was in the air prior to coming in contact with the spring and compressing it .13m. This one I'm having a rough time visualizing though, any tips you have would be great...thanks again
