A jack-in-the-box undergoes simple harmonic motion after it pops out of its box with a frequency of 4.0 Hz and an amplitude of 19 cm.
(a) What is the maximum acceleration experienced by the jack-in-the-box?
(b) If the mass of the jack-in-the-box is 0.180 kg, what is the maximum net force it experiences during the motion?
(c) If the initial phase angle is Π/3 rad, write an equation that describes the net force as a function of time. (Assume SI base units and the angles are in radians. Do not include units in your answer. Use the following as necessary: t.)
