2009 Tromeon - Drockw/Sole The mass m; enters from the left with velocity vy and strikes a mass m, > m; which is initially at rest. The collision between the blocks is perfectly elastic. The mass m; then compresses the spring an amount x. Immediately after colliding with m;, the mass m; stops and has zero velocity. The maximum energy stored in the spring is ...... the initial energy of m; . | Immediately after the collision, the energy of m; is ...... the initial energy of m; . Immediately after the collision, the momentum of m; is . the initial momentum of m; . In a head-on elastic collisions with an equal mass at rest, an object will come to rest. A head-on collision with a more massive object will cause the first object to rebound, while a head-on collisions with a lighter object will not stop the first object from moving forward. N - & 7 Three spherical masses are located in a plane at the positions shown below. Y (m) -5-4-3-2-106 12 3 45 X (m) The masses are Q=0.800 kg, R=0.400 kg, and S=0.700 kg. Calculate the x and y coordinates of the Center-of-Mass of this three mass system. Xem=[____ | Yem=[____]
