A heavy ball is thrown straight upward. After the ball leaves the thrower's hand, what forces act on the ball? a. A constant downward force from gravity, along with a steadily decreasing upward force from the thrower. b. A steadily decreasing upward force from the thrower on the way up, then a nearly constant force from gravity on the way down. c. A downward force of gravity that decreases substantially as the ball gains height, then increases substantially as the ball falls back downward. d. A steadily decreasing upward force from the thrower on the way up, then a steadily increasing force from gravity on the way down. e. A nearly constant downward force of gravity.

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?”
