Block A begins at the top of the track with an initial speed. It then slides on the track without friction going down to the bottom and back up to the second platform. Finally, it collides with a stationary block, B and the two stick together and continue to slide. Block A, with mass, mA= 0.75 kg is given an initial velocity, v0= 1.3 m/s. Block A slides without friction along a track downward from a platform at height h1=...

A rubber block (m= 20.0g) slides along a frictionless table at v=2.00m/s directly towards a steel block (m= 0.0500kg), which is at rest on the table. After an inelastic collision, in which 25% of the system's kinetic energy is lost, the rubber block rebounds the way it came at a reduced speed. Determine the speed of each block after the collision. (Is there a way to solve without quadratic?)

A block of mass m1 = 1.10 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.900 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.40 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...
