A vacationer gets into his outboard motorboat and leaves a dock on a river bank for a day of fishing. Just as he turns upstream, he hears a splash but pays no attention and continues cruising at normal speed. Unfortunately, only 10 minutes later does he realize that his (fortunately watertight) lunchbox is missing. He then turns downstream, with the motor still set at cruising speed. Luckily, he sights his lunchbox floating down the river and retrieves it at a point 1  km downstream of the dock. How long after turning around does he pick up his lunch? Give your answer in minutes

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
