A bullet (0.1 kg) initially moving at speed u is embedded inside block 1 (4 kg) initially at rest at A which travels 8 m in a rough region (uk = 0.2) to B at speed of 12 m/s, then travels to a frictionless region from B to C, then to a rough region (Uk = 0.2) after point C. Then bulletblock 1 collides with block 2 (15 kg) which is initially at rest and connected with a spring of...

A block having a mass of 5 kg is initially moving at a speed of 10 m/s in the positive x-direction when it experiences a head on collision with a second block having a mass of 8 kg that was initially moving in the negative x-direction with a speed of 3 m/s. After the collision the velocity of the larger, 8 kg, block is observed to be 5 m/s in the positive x-direction. The situations before and after the collision...
Question: An initially stationary block of mass 0.5kg is on an incline angled 20° above the horizontal. When released, it slides down the frictionless incline undergoing a vertical displacement of 4m and then travels across a rough horizontal surface to a spring constant 600 N/m. The block compresses the spring 20 cm from its equilibrium position before momentarily coming to a stop. A.) How fast was the block moving when it was at the base of the incline? B.) How...
