Acceleration down an inclined plane

Acceleration down an inclined plane. What is the maximum acceleration given angle theta, and what is the maximum speed obtained given ramp distance?

Damn just found this. This was a lot more intuitive than the other explanations I've been trying to find on the subject. Thank you.

When solving for Vf at the end you used the acceleration of gravity (9.8m/s^2) rather than the actual acceleration from the given angle which we calculated to be 2.2m/s^2

so Vf would be 
sqrt((2)*(2.2m/s^2)*(16.76))
=8.6m/s

Very cool demonstration tools and explanation! Thank you.

This man writes in to opposite direction. How incredible.

I want him as my professor - the explanation my prof gave me was just incmprehensible; now I got it :)

Ah, that weren't no mistake at the end with acceleration. Just a teacher using a deft trick to see who's paying attention. Well done, Mr. A. ;)

@ 1:20, marks the wrong angle as Theta.

[Teyros]

can someone please answer why he made the opposite side of the right angle gcosϴ? (when he drew the little diagram) shouldnt it be sinϴ because sinϴ is opposite the angle?

[nscspeedcubing]

there is an error in the calculation.. your components of g are wrong

[mamadoudiobetdiop]

If I am not wrong, the angle theta is not at the right place. However, this is a great option to use.

But what if the surface, on which the inclined plane is kept, is frictionless

[niloybasu]

Why are we putting g as accn in root 2 gh

[MO-lofe]

When calculating V final
acceleration should have been 2.2.. not 9.8
?!?

Matt you look like you're filming a horror movie 💀

Hi teacher, i'm with doubt for Vf did you say VF = √(2 aXf, but in the calc you you show (video time 5:00) a=9.8 = √(2(9.8)(16.75) = 8.60m/s, but I try it and the answer is 18.12m/s. I try using using a=2.2 = √(2(2.2)(16.75) = 8.60m/s now the answer is the same your. a = acceleration, right? Please could you solve me this doubt. Thanks for your videos and time, I appreciate your job!

is he writing backwards or am i tweaking

[baronstomper]

u creepy as hell but u so good at explaining physics

[burhanmaryam]

What is the thing he's writing on
