A massless spring (with force constant k = 192 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 = 58.1 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 5.3 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 = 0.89 m. show answer No Attempt 50% 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.
