[单选题]
94.40: A block of mass M is initr yd8ax8c xc08+ 0mbt+no:ldnially at restao:wyvqv 8a5erf(x 2 + on a frictionless floor, as shown in the accompanying figure. The block, attached to a massless spring with spring constant k, is initially at its equilibrium positionoaafv5 8vye+rx:(q2 w. 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. $x= \frac{mv}{\sqrt{(M+m)k}}$
