Solving Horizontally-Launched Projectile Problems

Mr. H shows how to analyze a physics problem involving a projectile launched horizontally from an elevated position. After discussing the concepts and formulas, three examples are done. Each example includes a different unknown variable - horizontal displacement (dx), vertical displacement (dy), and original horizontal velocity (Vox).

This video along with the one for angle launched projectiles made me become literally a pro at this topic

[@PhysicsclassroomVideos]

And great work on your part!

[@Dr_Doofenshmirts]

Thank you for explaining it clearer than my current teacher that expects us to instantly know what he's talking about without explaining it properly and expects no one to cheat

[@btsmochimi7924]

Thank you so much! The video is really really helpful. I tend to mismatch equations especially applying it in projectile motion problems and I end up confuse but the x and y chart is indeed helpful for me!

[@PhysicsclassroomVideos]

Thats a common problem. I'm glad you've found a trick to help.

Thank you, Mr. H. You're a great teacher. I literally just discovered your videos on the day before my final exam (T-T). It's a great help though.

[@PhysicsclassroomVideos]

I'm glad it helped

[@texasgirls1651]

I found this video today needing help with horizontally launched projectiles and nothing has made so much sense before thank you I will definitely be using this video and your action plan for practice Thank You, Mr. H!!

[@PhysicsclassroomVideos]

👍I'm glad you're taking advantage of the action plan.

[@jessicamoses2547]

Example 3 is just what I was looking for! Thanks!

[@PhysicsclassroomVideos]

You're welcome!

[@mireallasalim6644]

That wasn't only a life saver but also a grade saver :)

[@Andr3yo]

I got stuck on finding height and this was the only video that included this type of problem. Thank you!!

[@joellatriciapardillo3660]

Thank you for the STRATEGIES you gave, it really help me❤

[@nickandtom2487]

Thx so much. This made it so much easier to understand.

[@PhysicsclassroomVideos]

Glad it helped!

[@lilakohis]

THANK YOU !

[@Mooksie]

Omg thank you so much! It helped me understand the concept now

[@flavianonyango9978]

I've been greatly helped.... thanks a bunch🙏🙏🙏

[@Mooksie]

I love the idea of an action plan

[@PhysicsclassroomVideos]

If you can put the learning to practice, its going to stick more.

[@josephchingozi7940]

Thank you it's really helpful

[@flavianonyango9978]

This is so great 👍

[@amirbarjakli3383]

thx for explaining. I'm in second semester and my exam is in next month :)

What would the free body diagram be for a table with a book on it, I know that for the book there will be normal force going up and gravity going down, but what would the diagram be for the table and also the earth

[@HannahFreyfilm]

Thank you so much!! This saved me

[@PhysicsclassroomVideos]

I'm glad it did.

[@javiencaboi9239]

May I ask what brand your pen is? It's really nice!

[@ynl_rm3411]

Thank you

[@PhysicsclassroomVideos]

You're welcome.

My father and I like your hand writing

[@Urawizardharryy]

thanksss

[@bandukhoje2801]

You're Great !, Can you please answer me the answer of 1st question ???
(The cliff one)

[@PhysicsclassroomVideos]

All 3 answers are in the video.

[@theskywalkergaming4502]

Salamat tatay hahaha

[@nasimshapouri8609]

after watching your videos I like physics more

[@PhysicsclassroomVideos]

Best complement one could get. Thanks.

[@mahalima1500]

Where did you get the 4.9t²

[@santiagofernandez5604]

Why include the variable "a" in the chart if it is not part of any of the equations?

[@PhysicsclassroomVideos]

It is in most of the equations. It's just a constant instead of a variable. So it's actual value (9.8 m/s/s) is substituted into the equation in plave of the symbol.

excuse me but why is there 4.9

[@PhysicsclassroomVideos]

Its part of the 0.5*9.8*t^2 term
