The oscillation frequency of a pendulum is 2 Hz. Calculate the ball
Velocity passing through the equilibrium location if the thread deviates
The maximum angle is 30 0..

the main problem that i have is i have multiple ways to calculate and all of them give me different results for example if we know the time it takes to go to the center we can devide that distance with the time and we get the time.

the other one is the acceleration that is caused by gravity is it's force is spent on moving to the center and the force on the string sin(30)mg=F so we can get the acceleration that is the combination of this forces. if you know the time it's just sin(30)g*0.125

2 Hz gives length
then it's a trivial potential vs kinetic energy equation

3d ones is from the formula that is derived from work that the gravity does and the kinteic energy mgh=mv^2 /2 this comes out to v^2=2gL(1-sin(30))

i know but why do his formulas lead to such derastic results?
