Answer:
both cannonballs hit the ships with the same horizontal speed
Explanation:
Hello!
A parabolic motion is characterized in that its vertical component in Y is constantly changing, this is due to the constant downward acceleration of gravity.
When the movement starts the speed at Y is maximum, then when it reaches its maximum height point its speed is zero, and finally it begins to increase downwards until it touches the floor.
On the other hand, the horizontal speed remains constant AS THERE IS NO ACCELERATION IN HORIZONTAL DIRECTION.
therefore both cannonballs hit the ships with the same horizontal speed
regards!
