Question

I need help with C,D,E 

A mass of 0.38 kg is attached to a spring and set into oscillation on a horizontal frictionless surface. The simple harmonic motion of the mass is described by x(t) = (0.44 m)cos[(14 rad/s)t].
Determine the following.
(a) amplitude of oscillation for the oscillating mass
(b) force constant for the spring
How are the angular frequency and force constant of the spring related? N/m
(c) position of the mass after it has been oscillating for one half a period
How long does it take the oscillating mass to travel from the maximum positive displacement to the maximum negative displacement? m
(d) position of the mass one-third of a period after it has been released
(e) time it takes the mass to get to the position x =
-0.10 m after it has been released
