Question: A block of mass _m_ , after sliding down a frictionless incline, strikes another block of mass _M_ that is attached to a spring of spring constant _k_ (see below). The blocks stick together upon impact and travel together. (a) Find the compression of the spring in terms of _m_ , _M_ , _h_ , _g_ , and _k_ when the combination comes to rest. Hint: The speed of the combined blocks {m + M}\ \left( \left. v_{2} \right) \right. is based on the speed of block _m_ just prior to the collision with the block _M_ (v 1 ) based on the equation v_{2} = (m/m) + M\ \left( v_{1} \right) . This will be discussed further in the chapter on Linear Momentum and Collisions. (b) The loss of kinetic energy as a result of the bonding of the two masses upon impact is stored in the so- called binding energy of the two masses. Calculate the binding energy.
