Homework Statement
A 2 kg mass hangs from the end of a 1 meter long string which is Øxed at its other end. The mass is displaced so that the string is at 53° to the vertical and released (remember sin(53°) = cos(37°)=0.8). Find the magnitude of the total acceleration of the mass when the string is at 37°
to the vertical.
Homework Equations
T=2π√1/g), ω/2π=1/T, a=-ω2xmaxcos(ωt+phi)
The Attempt at a Solution
The period of the pendulum is ~2 seconds, so ω=π can plug that into a=-ω2xmaxcos(ωt+phi) and set phi=0.
I'm not sure how to find xmax, or even what it represents in this case
Alternatively I tried making a free body diagram and see the two forces are from gravity and the tension in the string
