A block 1 of mass M-20 kg collides with a block 2 (m-100 kg) moving with velocity v-20m/s in the negative direction of x-axis. They couple and move in the same direction as block 2 before the collision with speed v=1m/s. Calculate the velocity of the block 1 before the collision. How much of the initial kinetic energy was lost during the collision?
