An object of an unknown mass is attached to an ideal spring with force constant 120 N/m and is found to vibrate with a frequency of 6.00 Hz. Find (a) the period, (b) the angular frequency, and (c) the mass of this object.

T= 1/Frequency
angular freq= 2PI f
finally mass from this equation
Period=2PI sqrt(Mass/k)
