A canon ball of mass 10 kg is fired from a cannon located on the edge of a cliff overlooking the sea as shown below. The cannon is 45 m above sea level. The canon ball is fired at an angle of 15° from the horizontal with an initial speed of 250 m/s. Air resistance may be ignored What horizontal distance (in km) will it travel before it falls into the sea? answer = 3.35kN What will be its speed (in m/s) as it hits the surface of the sea? answer = 252m/s please show all working with explanantions

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?”
