After colliding, the block with mass M1 is moving to the right with speed 1.00 m/s
Which of the blocks underwent a larger magnitude of acceleration during the collision?
A. The block with mass M1.
B. The block with mass M2.
C. The magnitude of the acceleration was the same for both blocks.
D. The answer depends on how much kinetic energy was transferred out of the two-block system.
E. More information about the time of the collision is required to answer the question.
