A spring stresses by 15cm when a mass of 300g is hang down from it, if the spring is then string is stressed additional 10cm amd released, calculate
1 the string constant
2 the amplitude of the oscillation
3 the maximum velocity
4 the maximum acceleration
5 the period of oscillation
6 the frequency?

The first thing to note is that we have to convert all units to SI units.
Follow
• EmX: Amplitude is the maximum displacement.
This one mustn't be in SI unit.

As for the next question we can't use the mass (300g) since it's obviously not what made the spring, to stretch the additional 10cm.

So we need to find the additional force and add it to the initial mass to get the total mass that brought about the amplitude.

See below for (b) and (c)
