    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=...
