Reason for log move in opposite direction if you walk along a log floating on a lake.
Answer to Problem 7Q
Solution:
According to
Explanation of Solution
Newton’s third law of motion states that for every action, there is an equal and opposite reaction.
If you take a step forward on the log, you exert a force on the log. Then log will move in the opposite direction of the walk, because of the force you exert on the log (i.e. the forward force of your foot causes the log to be pushed in the opposite direction i.e. backward).
As you push the log going in one direction, the opposite reaction will be pushing your body forward and would be to push the log backward.
