94.40: A block of mass M is iy6bedwt8z+n4uy ( k1anit/9tu:lbh5u sc m*h j:sially at rest on a frictionless floor, as shown in the accompanying figure. The block, attached to a masslus*h :j5 lsbtu9hmc/: ess 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. $x= \frac{mv}{\sqrt{(M+m)k}}$
