i. On each of the dots, which represent the blocks while they are in contact during the collision, draw a single arrow to indicate the direction of the net force, if any, exerted on each block. The net force must be represented by a distinct arrow starting on, and pointing away from, the appropriate dot. If the net force is zero for either block, write “zero” under the dot representing that block.

The correct answer is antinodes
