A block of mass m2 = 7.5 kg, at rest on a horizontal surface that has negligible friction, is connected to a spring which is initially not stretched or compressed. The other end of the spring is fixed to a wall, and the spring constant is k = 180 N/m. Another block of mass m1 = 4.5 kg and speed v1=3.3 m/s collides with the 7.5 kg block. The blocks stick together, and compress the spring. What is the maximum compression of the spring?

Problem 16: 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 = 50.1 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 6.6 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 = 0.97 m. Part (b) In meters per second, what is the speed of the bullet v before it enters the block? Part (c) What is the frequency f (in Hz) of the resulting periodic motion of the block/bullet and spring system?
A spring with a spring constant 247 N/m is initially compressed by a distance of 0.044 m from its equilibrium position. A mass of 0.059 kg is then held against the compressed spring and released from rest while upon a horizontal, frictionless surface. Assuming that the spring then pushes the mass across the surface, with speed does the mass leave the spring? Assume proper SI Units.
