(11%) Problem 2: A massless spring (with force constant k = 199 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 = 53.8 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m =7.2 g into the block along the spring axis. After the gun is fired, the bullet gets embedded in the block, and the spring is compressed a maximum distance d = 0.98 m. m M ▷ 33 % Part (a) 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. kd² v=√√k(M+m) V= √k(M + m) d M V= m M V= m √(M + m) V= √k(M + m) V= √k(M + m) d m Submit Hint Feedback I give spl 33% Part (b) In meters per second, what is the speed of the bullet v before it enters the block? 33% Part (e) What is the frequency f(in Hz) of the resulting periodic motion of the block/bullet and spring system?
