Answer:
0.67 s
Explanation:
This is a simple harmonic motion (SHM).
The displacement, , of an SHM is given by
A is the amplitude and is the angular frequency.
We could use a sine function, in which case we will include a phase angle, to indicate that the oscillation began from a non-equilibrium point. We are using the cosine function for this particular case because the oscillation began from an extreme end, which is one-quarter of a single oscillation, when measured from the equilibrium point. One-quarter of an oscillation corresponds to a phase angle of 90° or radian.
From trigonometry, if A and B are complementary.
At ,
So
At ,
The period, , is related to
by
When an object absorbs an amount of energy equal to Q, its temperature raises by 
following the formula
where m is the mass of the object and
is the specific heat capacity of the material.
In our problem, we have
, 
and 
, so we can re-arrange the formula and substitute the numbers to find the specific heat capacity of the metal:
where m is the mass of the object and
In our problem, we have
