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?”

Question

5. Three objects of the same mass are launched separately at different angles (30, 45 and
60). Which of the three will have the longest range provided they have the same initial
velocity? Why?

resistance? Why?
