A1.00-kg block (mass m) and a second block (mass M) are

Chapter , Problem 111

(choose chapter or problem)

A 1.00-kg block (mass m ) and a second block (mass M) are both initially at rest on a frictionless inclined plane (Figure 8-56). Mass M rests against a spring that has a force constant of \(11.0 \mathrm{kN} / \mathrm{m}\). The distance along the plane between the two blocks is \(4.00 \mathrm{~m}\). The \(1.00-\mathrm{kg}\) block is released, making an elastic collision with the larger block. The \(1.00-\mathrm{kg}\) block then rebounds a distance of \(2.56 \mathrm{~m}\) back up the inclined plane. The block of mass M momentarily comes to rest \(4.00 \mathrm{~cm}\) from its initial position. Find M.
