Suppose a man jumps forward toward a dock from a small boat that is not securely anchored. What happens to the horizontal motion of both the man and the boat if the boat has less mass than the man? Ignore the effect of the friction between the water and the boat in this case.
Describe what would be observed.
Explain what was observed with the horizontal motion of the man and the boat in terms of Newton's Laws of Motion.
