Question:

Why does a canoe move forward when the canoeist pushes water backwards with their paddle and why does it move faster when they push harder? [Pg. No. 94]

Answer: Verified

When the canoeist pushes the water backwards with the paddle, the water exerts an equal and opposite force on the canoe. This opposite force pushes the canoe forward. When the canoeist pushes the water harder, the backward force on the water increases, so the forward force on the canoe also increases. Hence, the canoe moves faster.
