การเคลื่อนที่แบบโปรเจคไตล์

Two cannon (at different height) aim at each other.
What will happen if both cannon fire at the same time?
Want to know the answer? Just press the start button

You can change the position of cannons

Left cannonกGclick at the blue dot and drag it up and down.
right cannon: click at lower right corner and drag it left and right
Both of them will adjust angle to aim at each other.

click the red arrow and drag it left/right or up/down.

The length of the red arrow is represent the displacement of cannonball

in one second (under no gravity)

กHกHกH As long as the velocity is large enough ,
the cannonball will hit each otherกIกIกI
Click the right mouse button to continue.

If the difference in height is h, horizontal distance is w,
What is the requirement for the velocity v₁,v₂กH

Want to know the reasonกH Select show checkbox

to show the trajectory of both cannonball when there is no gravity,

and the effect of the gravity to the cannonball(yellow line).

How to pause the animation

Press the left mouse button to pause, release it to continue
If you click the right mouse button, you need to click it again to continue.
What if you click right mouse button, then press the left mouse button?
