A body oscillates with simple harmonic motion along the x-axis.Itsdisplacement varies
with time according to the equation
x(t) = A sin(wt + o) .
If
A = 5 m,
w = 2.931 rad/s,
and o = 1.0472 rad,
what is the acceleration of the body at t = 2 s?

Note: The argument of the sine function is in radians ratherthandegrees.
Answer in units of m/s2.
