A 265g mass attached to a horizontal spring oscillates at a frequency of 1.00Hz . At t =0s, the mass is at x= 4.20cm and has vx = − 1*.0cm/s. Determine the position at t= 3.60s.

So I already found that...

The period is 1.0000 s

The angular frequency is 6.2832 rad/s

The amplitude is 5.1753×10^−2 m

The phase constant is 0.6240 rad

The maximum speed is 0.325 m/s

The maximum acceleration 2.04 m/s^2

The total energy is 1.40×10^−2 J

The position at t= 3.60 s is….????

nvm I figured it out...

the answer was -1.6*10^-2 m
Youve got the wrong amplitude
