from this equation i get the amplitude is 8 cm, it's a sine function so i guess it has to be a harmonic oscillation

i haven't had physics in a while so not really getting anywhere

-i need to know T (time for one oscillation)
-the frequency f which is 1/T
-Vt and At equations, i know i have to differentiate the given equation but i can't figure out how exactly
-the velocity (speed) and acceleration on t = 1s
-and the Vmax and Amax

hi sam2711! welcome to pf! :smile:
i need to know T (time for one oscillation)

you don't need to differentiate for that …

the period T is the the value of t for which the angle (the phase) is 2π (= 360°) :wink:

… i know i have to differentiate the given equation but i can't figure out how exactly

use the chain rule

show us what you get :smile:
