(13%) Problem 8: A massless spring (with force constant k = 182 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 = 57 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 7.9 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 = 0.93 m. m M Otheexpertta.com 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. m V VK(M + m) Correct! 50% Part (b) In meters per second, what is the speed of the bullet v before it enters the block?
