cool now i got it. tx a lot for helping me man

so the period is 1/f = 5 E-13 5E-13/ 4 = 1.25E-13 v1 = v0 + at ( i thought we were suppose to use this only when the a is constant but anyway 138 = a(1.25 E-13) a = 1.1 E 15 but the answer key says that the answer should be 1.7 E 15... so i am wondering is the answer close enough or...

whats the time tho?

we know that w = 2 pi / T w = 9.97 and we also know, w squared = k/m hence solving for k you get k = 1.54 N/m

ohh i see! anyway i can find the max acceleration too?

ohh yea thank you so much and is there any way we can find the max acceleration too?

Homework Statement Atoms in a solid are not stationary, but vibrate about their equilibrium positions. Typically, the frequency of vibration is about f = 2 E12 Hz and the amplitude is about 1.1 E-11m. For a typical atom, what is its (a) maximum speed? Homework Equations T= 1/f. v = change...

agreed :D

its high school non-calculus based physics

yea i put the wrong equation. sorry about that. and i thought everyone knows drop zone so didnt try to be too specific. Anyway, i haven't learned calculus based physics So, what i did is completely wrong? Or if there is any other way to find the objects mass then it would be helpful too

Homework Statement Its the drop zone in kings dominion d = 82.9 m initial velocity = 0 final velocity (before the brakes are applied) = 32.19 m/s i know there is gravity downward and airresistance upward. I need to find the mass of the object. Homework Equations First i found...

just wondering what's the formulae if its not constant

yes its good

its when u feel weightless

just like a ball moving in a uniform circular velcoity
