Physics Lesson: Acceleration Down Ramps w/Friction Part 2 for high school

[AnthBalce]

this single-handedly keeps my Physics mark up! Thank you sooo much

@AnthBalce Thanks for taking the time to let us know you liked our videos.

what if both kinetic and static μ was given? how would you solve this?? Thanks

[TreThesk]

your μ is immaculate.

[ericlam2728]

what if you dont know the mass ?

You could make your videos perfect by having a little more resolution. It's sometimes hard to read what you write on the board.

My teacher doesn't teach at all! Thank you so much for catching me up. Keep it up

[PhysicsEH]

@badgerbirk Glad we could help

@b68dv The gravity on the object was Fg which is equal to Fg= mg or mass*9.8. To find the y component of Fg you use

Fgy = FgCos30 because you have the hypotenuse and angle and need the adjacent. Since Fg = mg then

Fgy = mgCos30 = 5*9.8Cos 30 = 42.4N

I hope this helps.

[PhysicsEH]

We made a not on it to fix it. Thanks for letting us know.

[maciejl06]

yah, you should really fix that mistake, cause you got Fgy as 49 despite it being 42.4, but your answer turned out correct in the end. The mistake kinda reflects badly upon your school...

[anty45]

everybody makes mistakes it doesn't reflect badly upon their school , just be thankful to these videos

[maciejl06]

@anty45 yup, i know many people make mistakes, and i understand, but it's and educational video,though i think i came off a bit rude, that wasn't intentional. these videos actually help me a lot, thank you.

Hello, I was just wondering if you made a mistake with the Fgy calqulation because I got 42.4N instead of the 49N you got.
