In the figure, block 2 (mass 1.20 kg) is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 228 N/m. The other end of the spring is fixed to a wall. Block 1 (mass 1.80 kg), traveling at speed v1 = 4.10 m/s, collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed? Number i UnitsSpeed amplifier. In the figure block 1 of mass m, slides along an x axis on a frictionless floor at speed 0.501 m/s. Then it undergoes a one- dimensional elastic collision with stationary block 2 of mass m2 = 0.632 m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass m3 = 0.495 m2. (a) What then is the speed of block 3? Are (b) the speed, (c) the kinetic energy, and (d) the momentum of block greater than, less than, or the same as the initial values for block 1? 2 3 (a) Number Units (b) (c) (d)
