An object in simple harmonic motion has amplitude 4.8cm and frequency 3.4Hz , and at t = 0s it passes through the equilibrium point moving to the right.
Write the function that describes the object's position.
a) x(t) = (2.4 cm) cos((6.8 π rad/s)t - π/2 rad)
b) x(t) = (4.8 cm) cos((3.4 π rad/s)t)
c) x(t) = (4.8 cm) cos((6.8 π rad/s)t - π/2 rad)
d) x(t) = (2.4 cm) cos((6.8 π rad/s)t)
