[xkirkx]

Homework Statement

A block of mass M rests on a frictionless horizontal surface and is attached to a wall by a spring of spring constant k. A blob of putty of mass m and horizontal speed v collides with and sticks to the block. Find the maximum compression of the spring.

can anyone help?

Too funny. I saw the title of this thread, and thought a cat was the projectile!

Welcome to the PF. Use total energy to solve the problem. TE = KE + PE.
