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.

Select the most appropriate answer. O Bemoulli eg was derived by applying Newton's 2nd law to a particle and then integrating along a streamline: while Energy eg was derived using the 1st law of thermodynamics & consequently the Reynolds transoort theorem. Energy eg includes both mechanical.and thermal eneray, while Bernouli eg involves only.mechanical eneray. Bernoulli eg is applied by selecting two.points (can be anywhere) on a streamline (irrotational flow) and then equating terms at those points, while Energy eg is applied by selecting an inlet & on outlet sections and then equating terms at those sections. Energy eg applies to steady. incompressible. viscous flow with additional energies through the pumR. turbine, and heat engines: while Bemoulli eg applies to steady. incompressible, and inviscid flow (h = 0, a = 1). Under special circumstances, Bernoulli eg converts into Energy eg if pump or turbine added along the streamline Bernouli eg was derived by applying Newtan's 2nd law…
