Homework Help: Simple harmonic motion , Particle

  1. Sep 24, 2008 #1
    1. The problem statement, all variables and given/known data

    A 150 grams particle oscillating in SHM travels 24 cm between the two extreme points in its motion with an average speed of 60cm/s

    a) angular frequency
    b) the maximum force on the particle
    C) the maximum speed

    3. The attempt at a solution

    My first question would be what approach to use ?? This is the first problem I do with a particle. I am having trouble just finding the angular frequency and I don't even know if am suppose to use the weight for the first answer.

    My second question is , what do they mean by maximum force on the particle ?
    is it somewhat like a spring Fsp = kx ?

    Hi EvilBunny! :smile:

    SHM means the acceleration is proportional to (minus) the distance …

    x'' = -kx.

    You should be able to get everything from that (and no, you only need the weight for part b). :smile:
