A 2.30 kg mass on a spring has displacement as a function of time given by the equation

x(t) = (7.40 cm)cos[(4.16)t-2.42]

a) Find the time for one complete vibration.

The back of the book had this same equation but a different mass, so I was able to figure out the answer was 1.51 seconds that way.

This was originally a 10 part question and I can do all the parts after a, but I can't find a.

I tried plugging in "1.00" but that is wrong, and I used that for another part of the question. Equations such as T= 2pi*sqr(k/m) always have two variables, so I don't know what I am doing wrong.

Please help. Thanks.
