block 2 (mass 1.30 kg) is at rest on a frictionless surface andtouching the end of an unstretched spring of spring constant 292N/m. The other end of the spring is fixed to a wall. Block 1 (mass1.40 kg), traveling at speed v1 = 5.90 m/s,collides with block 2, and the two blocks stick together. When the blocks momentarily stop, by what distance is the spring compressed?
A rope of negligible mass is wrapped around a 225 kg solid cylinder of radius 0.40 m. The cylinder is suspended some meters off the ground with its axis oriented horizontally, and turns on that axis without friction.
