Simple harmonic motion , Particle

Homework Statement

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

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

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!

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).
