Solving Angle-Launched Projectile Problems

Mr. H shows how to analyze a physics problem involving a projectile launched from ground level at an angle, rising up and falling back to the original height. After discussing the concepts and formulas, two examples are done to calculate the time in the air, the horizontal displacement, and the height at the peak.
The solution to the second example can be found here: • Example 2 Solution

I cannot thank you enough, this was extremely helpful. I now feel confident going into my test tomorrow!

[@PhysicsclassroomVideos]

I hope you ace that test.

[@hexader]

i love how in the end, you put in a summary and the equations used. thanks, it makes it so much easier

[@harshapandaraboyina]

very helpful, clearly stated and well explained

[@Reign-rk2hv]

This is the most easy lesson i have ever attended. Thank you sir.

[@PhysicsclassroomVideos]

Youre welcome.

[@franzvicsandoval5432]

Been watching your videos a lot lately. The practice problems really help. Thanks for the content :D

[@PhysicsclassroomVideos]

I'm glad its helping. And you're doing the right thing if you're taking advantage of the practice.

[@caelanhassett8392]

This video was extremely helpful, thank you for taking the time to make it :) I have my first exam in a week and I've been struggling to understand concepts related to projectile motion, but you made it very easy for me to understand and I already feel more confident that I'll be able to do well on my exam!

I have been trying so hard to understand this topic and you sir, have helped me like no one . Im finally getting the idea of it thanks to your explanations. Thanks a lot for the material!!!!

[@PhysicsclassroomVideos]

Thanks for the kind words. You made my day.

VERY nice. I'm helping my goddaughter with this, and I couldn't make heads or tails of what to do based on her notes!

How would I find the Distance travelled in the X axis if the projectile is launched from a height that is not zero?

[@helen7277]

how do you find the original velocity if you aren’t given the angle, but you do have Voy and Vox?

[@PhysicsclassroomVideos]

Pythagoras theorem

[@helen7277]

@@PhysicsclassroomVideos That's what I thought, but when I tried it for one of my online problems, it kept saying they were wrong. I'll have to keep trying, thank you!

[@rmazam700]

How about the problems related to projectile launched at an angle from a height say a cliff? Are there any problems related to it? I couldn't find on your website.

[@PhysicsclassroomVideos]

You will find some in the calculator pad and in the review session.

[@rmazam700]

@@PhysicsclassroomVideos Thank you for your prompt reply. I learn a lot from your website and youtube.

[@GraceDumplings]

So for the equation on number 5, I always thought u had to use an equation with acceleration too?

[@PhysicsclassroomVideos]

Nope. There are 4 equations and you use whatever equation you need to use depending on what quantities are given in what you are looking for There are 4 equations and you use whatever equation you need to use depending on what quantities are given and what you are looking to calculate.

[@GraceDumplings]

@@PhysicsclassroomVideos oh ok i just thought that when dealing with the y axis, we had to take the acceleration into account

[@nikcyc.a.362]

How I calculate the time if only I know the Vox and Voy value?

[@PhysicsclassroomVideos]

Calculate the top from a=-9.8, the voy value and vfy=0. Then double tup to get ttotal.

[@judevinlyalmazar6198]

can you slow down the talking?? what's the rush? i cant understand anything.

[@PhysicsclassroomVideos]

I actually get both requests. On this video I definitely overdid the "speed up". You can always control the speed yourself.

[@davistwenter6875]

bro u need to slow the heck down

[@Mooksie]

it was good for me
