Simple harmonic motion Q Watch
I was trying this question out but don't think I've got to the right answer and my graph seems a bit off.. please can someone have a look at this! Please see my workings and question attached.
Thanks in advance.
Note SHM eqn w/o phase shift i.e) starting at origin, is x(t) = Asin(wt). From +A is pi/2 phase shift, so x(t) = Asin(wt + pi/2) = Acos(wt).
More importantly: T = 1/f = 0.6 s (1 d.p) but your graph shows T of over 2 s. The horiz axis should be time (s).
