Clicker Question 9 A bullet of mass m is traveling to the left with speed v when it embeds itself in a block of mass M initially at rest. The block sits on a frictionless surface and is connected to a spring of stiffness k. What is the compression s of the spring when the bullet and block come to rest a moment after the impact? A. s2 = 12 M k B. s2 = 12" K C. s2 = 121m k M D. s2 = 121 m2 k M+m E. $2 =0 For maximally inelastic collisions, you only need momentum conservation. Why
