94.40: A block of mass M is initially at rgof2+r lsv *b:8*jt4s t0r-xerct kw8est on a frictionless floor, asz ; zty aw7;kwr85ms.z shown in the accompanying figure. The block, attached to a massless spring with spring constantr;z7zka5w .z8m ty ;sw 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. $x= \frac{(M+m)v}{\sqrt{mk}}$
