A 4.020-gram bullet is projected horizontally to a block of timber that rest on a horizontal floor. The timber is attached to a spring and the spring is bolted to the vertical wall, as shown in the figure. If the maximum displacement of the block at impact is 0.035 meter and the stiffness of the spring is k = 315,830.996 N/m, what is the speed of the bullet when it hit the timber? Assume that the spring has no mass and that there are no loses at impact.
