94.40: A block of mass M is initially at rest on a frictionless .1e uxfn7sh1;:p/1 zhroflw h4pt. oa flo ;1 wee 4mq*lhgmgd/ ,;zfokb*or, as shown in the accompanying figure. The block, attached to a mass k1lhwfd /gb zm4*;o,q gee*;m less spring with spring constant k, is initially at its equilibrium position. An arrow with mass m and velocity v is shot into the block. The arrow sticks in the block. What is the maximum compression of the spring?
A. $x= v\frac{\sqrt{m}}{k}$
B. $x= v\frac{\sqrt{k}}{m}$
C. $x= v\frac{\sqrt{M+m}}{k}$
D. $x= \frac{(M+m)v}{\sqrt{mk}}$
E. $x= \frac{mv}{\sqrt{(M+m)k}}$
