Fnet = FL - Fg ma = Fl - Fg (0.211)(21.7^2/25.6) = Fl - mg oh, i see it now, i was going too fast. the person who solved it just put the mass to multiple the v^2 directly. thank you for making me realize

no its not about gravity i think i didnt explain myself clearly. in the photo i sent, i indicated an arrow pointing to "m" of the mv^2/r. im just confused on why the "m" is there when the standard equation for centripetal acceleration is v^2 /r

this question was in my textbook and i didn't know how to do it so i searched it up online and found that picture explaining how to solve the problem

How come the solution requires you to do mv^2/4 when the formula is just v^2 /r?

no it doesnt. depending on which direction you are moving you will feel you're a different weight

won't the upwards force have to be greater than the force of gravity so that the elevator can accelerate upwards

I am having trouble coming up with a FBD. I know there is a Fg, Fn, friction, and applied force on the masses, but would there be another force going upwards because of the acceleration?
