(10%) Problem 2: A massless spring (with force constant k = 195 N/m) connects a wall and a block of wood. The system is initially at rest, with the spring unstretched. The block has mass M = 5 6 .5 g and is able to move without friction on a table. A gun is positioned to re a bullet of mass m = 9.9 g into the block along the spring axis' After the gun is red, the bullet gets embedded in the block, and the spring is compressed at maximum distance d = 0.85 m. l} A 33 % Part (3) Find an equation for the speed of the bullet v, just before it hits the block, in terms of the variables given in the problem statement f\" "X A Grade Summary \\ i x i Deductions 0% Potential 100% d d v__ 17; (M+m) \"=Evk(M+m) Submissions Attempts remaining: g -C' 'C- C (20% per attempt) detailed view Submit Hint _ I give up!
