A battleship 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.
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
Solar energy; It benefits life because it does not produce greenhouse chemicals that are dangerous to the evironment, it uses the hot light of the plasma from the sun to pass through the solar panels, form there it can be stored and used in batteries already built in, it also provides lots of money savings troughout the seasons, and it can save 155 dollars a year.
