Question:

A block of mass 1.10 kg is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 241 N/m. The other end of the spring is fixed to a wall. Another block of mass 2.00 kg, traveling at 5.20 m/s, collides with the first block, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?

Energy Stored by a Spring:

Let a spring of constant k is acted upon by a force such that it got compressed by a distance x . Then the potential energy stored by the spring is given by {eq}E_P= \frac{1}{2}kx^2 {/eq}

Answer and Explanation:

Given that a block of mass {eq}m_1= 1.10 kg {/eq} is at rest on a frictionless surface and touching the end of an unstretched spring of spring...
