Simple Harmonic Motion - Speed

[Jess_18033152]

Homework Statement

Calculate the speed of the block in SHM as it moves through equilibrium position.

k= 45.08248265 N/m
m of block = 0.505kg
T = 0.665s

Homework Equations

w= the square root of (k/m) ?

The Attempt at a Solution

w = the square root of (45.08248265/0.505)
= 9.448398958
= 9.45 (what units for SHM?) (3sf)

Is this the equation I use? And what are the units for speed when in SHM?

The quantity w is not a speed, it is an angular velocity. You should be able to deduce its units from how it is constructed.

Also, the problem does not contain sufficient information to give you the requested information.

What equation would you suggest I use then?

For what?

To calculate speed for an object in SHM as it moves through equilibrium position, given m of object= 0.505kg, k= 45.08248265, T (period) = 0.665s ?

As I already said, you cannot.

Sorry, worked out how to do it now, it required me using the kinetic energy I had worked out in the previous question. Thank you though :)

So, for the future, please give the full problem statement as required by the homework guidelines. You cannot expect us to guess information that you are not giving us.
