The cannon and the ball are moving with constant velocity in the horizontal plane all during this experiment. The cannon pushed the ball UP. It did not change the velocity horizontal plane.
If you drop a big bomb out of your low flying aircraft, you better speed up or turn after releasing the bomb or it will go off right under you.
a spring loaded "cannon" on a wheeled car fires a metal ball vertically. the car is given a push and set in motion horizontally with a constant velocity. A pin is pulled with a string to launch the ball, which travels upward and then falls back into the moving cannon everytime. why does the ball always fall back into the cannon? explain
