94.40: A block of masvdxqj g37/9vtk.+-r; iu3aqyxy vh3 xs M is initially at rest on a fricta6 mub61:ackn0x; xhq ionless floor, as shown in the accompanying figure. The block, attached toqabux061 ac x: k;m6hn a massless 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. $x= \frac{(M+m)v}{\sqrt{mk}}$
