Abattleship simultaneously fires two shells toward two identical enemy ships. one shell hits ship a, which is close by, and the other hits ship b, which is farther away. the two shells are fired at the same speed. assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is .now, consider both shells are fired at an angle greater than 45 degrees with respect to the horizontal. remember that enemy ship a is closer than enemy ship bwhich shell is launched with a greater horizontal velocity, ? a. ab. bc. both shells are launched with the same horizontal velocity.

Ответ:
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!
