5.35 blocks a and b are identical and each have a mass of 10 kg. block b is at rest when it is hit by block a which is moving with velocity va-6 m/s just before impact. blocks a and b stick together after the impact, and you may neglect friction during the impact. after the impact, the velocity of blocks a and b decreases due to friction. the coefficient of kinetic friction between all surfaces is -0.20. (a) determine the velocity of block a and b immediately after a hits b. (b) determine the impulse of the force of block a on block b during the impact. (c) determine the time required for the velocity of the blocks to drop to 1 m/s (d) determine the distance traveled by the blocks during this time interval. before the impact after the impact, blocks a and b travel together. 6 m/s
