A body moves in a simple harmonic motion and the following graph gives the variation of its displacement x with time t.
a) Write an equation to represent the given simple harmonic motion.
b) Find the time duration in the first cycle when the body is located above a displacement of 0.25 m.
[ x = xo sin (1.05 t) , Δt = 1.9 s ]
