Two blocks are travelling toward each other. The first has a speed of 10 cm/s and thesecond a speed of 60 cm/s. After the collision the second is observed to be travelling with aspeed of 20 cm/s in the direction opposite to its initial velocity. If the weight of the firstblock is twice that of the second, determine the velocity of the first block after collision. A. 30 cm/s to the left B. – 60 cm/s C. 20 cm/s to the right D. 30cm/s to the right
