In the picture, cannonball A was launched at 10 m/s at 60°, and B was launched at 18 m/s at 25°. The cannonball that hit the ground first was
A, because it had less total velocity.
B, because it had more total velocity.
A, because it had less initial vertical velocity.
B, because it had less initial vertical velocity.
