Energy and Momentum: On a frictionless horizontal surface, a 1.50-kg mass traveling at 3.50 m/s suddenly collides with and sticks to a 3.00-kg mass that is initially at rest, as shown in the figure. This system then runs into an ideal spring of force constant (spring constant) 50.0 N/cm.(a) What will be the maximum compression distance of the spring?(b) How much mechanical energy is lost during this process? During which parts of the process (the collision and compression of the spring) is this energy lost?
What will be an ideal response?
(a) 3.50 cm, (b) 6.13 J during the inelastic collision
