I'm having a hard time figuring out how to solve part e of this question. Detailed steps would be a tremendous help!

A mass of 0.12 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) = (0.36 m)cos[(20 rad/s)t]. Determine the following.
(a) amplitude of oscillation for the oscillating mass
.36
✔ m
(b) force constant for the spring
48
N/m
(c) position of the mass after it has been oscillating for one half a period
-.36
m
(d) position of the mass one-third of a period after it has been released
-.18
m
(e) time it takes the mass to get to the position x = -0.10 m after it has been released
.12
X
How can you determine the time for the oscillating mass to get to a specific position from an expression for the position of the object at any time? s
