This shows that the motion of a book launched off a table

Now if you put this vertical and horizontal motion together at the same time, you get projectile motion. The key to projectile motion is the idea that the vertical motion and the horizontal motion are essentially independent of each other Grain oil hoses suppliers. You can try a very simple and fun experiment. Set a book on the edge of a table so it is just about to fall off. Now get another book and slide it so it barely collides with the book on the edge. What should happen is that both books will fall off the table at the same time but with different horizontal speeds. However, since both books start at the same height with the same vertical speed, they will hit the ground at the same time.

This shows that the motion of a book launched off a table is a.bination of vertical and horizontal motions. The horizontal motion is at a constant speed and the vertical motion accelerates. Here is a diagram that shows this idea.The red dots show the motion of a ball. The green dots show the motion of a ball with the exact same horizontal speed as the red ball. Finally, the blue dots show a ball with the same vertical motion as the red ball.

But what does this have to do with range? I'm getting there. I assume that the starting speed of the water is the same no matter what angle it is launched at. So, how do you make the water go the farthest? One idea would be to shoot it.pletely horizontal. In this case, all of the speed of the water would be in the horizontal direction. However, it wouldn't go very far. Tank truck hoses suppliers? Because the water wouldn't be in the air for any significant time. You need to keep the water in the air for as long as possible.

Well, then you could shoot the water straight up. That would keep it in the air for the longest time. True. However, in that case there would be no horizontal.ponent of the water's velocity so it wouldn't go horizontally at all. There needs to be some balance between time in the air and horizontal motion. That balance happens to be at a launch angle of 45°. Here is a much more detailed derivation of this maximum range.
