Fоr the fоllоwing аrrаngements of blocks, one block is initiаlly moving and the others are at rest. Each block is separated by 30 cm and you can treat each block as a point mass. (a) Calculate the initial distance between the 2 kg block and the center of mass of the system.(b) If the blocks stick together after each collision, calculate the final speed of the 5 kg block.(c) If the blocks bounce off each other elastically, calculate how fast the 4 kg block will be moving after it collides with the 5 kg block.
