The system is initially at rest, with the spring unstretched. The block has mass M= 54.3 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 5.5 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 = 0.91 m. m M Otheexpertta.com ed ed ed 4 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.

The initial speed of the bullet is 357 m/s. The bullet embeds itself into the block and the bullet and block move together as one unit after the collision. 4 50% Part (a) What is the speed (in m/s) of the bullet-block combination after the collision?
