Homework Statement
Hi
I have two problems i need to solve mainly 1, but i need to check if 2a and 2b is correct
here it is:
A simple harmonics oscillator has an amplitude of 0,1m.At what displacement will its kinetic and potential energies be equala) What is the force due to the atmosphere...
Well when going upward you add weight since your pushed "into the seat", and down you take weight when the seat accelerate away from you.
So it would be F = mg+ma at the top since its "added weight"
45kg*9,82m/s^2+45*1,578m/s^2= 512,91N
And when you go down it will be the same but with (-)...
Oh yeah it was -2 not -1. Spelling error.
I Used for omega, ω = \frac{(2π*3)}{60}
The motions are up and down verticaly, but not sure if that formula is right or if i need to add other things to it
