welcome to pf!

hi pymn_nzr! welcome to pf!

(try using the X² and X₂ buttons just above the Reply box )

show us what you've tried, and where you're stuck, and then we'll know how to help!

(btw, what does "slither" mean? is the sphere rolling without slipping? )

hi pymn_nzr!

(please always reply on the thread, not by private message )

I solve it…its so easy…but I want all the dynamic questions are in this page( with answers)

If you have more dynamic questions put them in this page.

your english is a little difficult to understand

if you have more questions that you need help with, just start a new thread (preferably one for each question)

is it correct?

$$Y=\frac{g\sin \alpha }{2V_{0}^{2}(1-\frac{I}{mR^{2}})}X^{2}$$

i don't have time to check it properly , because I'm going out in a few minutes,

but i think that minus on the bottom should be a plus
