Question

Present all of your work as clearly and neatly as possible. Please draw a box around your final answer. If you consistently and correctly show all units throughout a problem, you will get one bonus point for that problem. If your significant figures are correct throughout a problem, you will get an additional bonus point. Block 1 collides with two different blocks. In case A, block 1 collides with block 2. In case B, block 1 collides with block 3. Block 1 is the same in both cases. Longer velocity vectors indicate greater speed. (a) Rank the mass of the three blocks, greatest first. Explain brielfy. (b) Is the magnitude of the total momentum of both blocks in case A greater than, less than, or equal to the total momentum of both blocks in case B? Explain briefly.

Explanation / Answer

The masses in decreasing order are

3 ,1 , 2

If m2v2= m3v3, then the total momentum is same in both cases
