# What is horizontal displacement calculation

You use vertical velocity for problems that include an angle of trajectory. My initial velocity in the y direction is zero. If a projectile is launched with an initial vertical velocity of 19. Vertically this person starts with no initial velocity.

## Horizontally launched projectile

Follow Us. But that's after you leave the cliff. So we have -29. So if you solve this you get that the time it took is 2. To log in and use all the features of Khan Academy, please enable JavaScript in your browser.

## Total displacement for projectile

We Would Like to Suggest... Thus, if the horizontal displacement x of a projectile were represented by an equation, then that equation would be written as. Articles Ebooks. I mean a boring example, it's just a ball rolling off of a table. You might want to say that delta y is positive 30 but you would be wrong, and the reason is, this person fell downward 30 meters.

## Describing Projectiles With Numbers: (Horizontal and Vertical Displacement)

We can use the same formula. The problem won't say, "Find the distance for a cliff diver "assuming the initial velocity in the y direction was zero. We want to know, here's the question you might get asked: Retrieved from https: We're talking about right as you leave the cliff.

Think about it. Now we will investigate the manner in which the horizontal and vertical components of a projectile's displacement vary with time. Let me write this down So we have a horizontal displacement of 29. A negative horizontal velocity means that the object moved backward from its original position.
