A 1.8 kg object oscillates at the end of a vertically hanging light spring once every 0.40 s . Part A Write down the equation giving its position y (+ upward) as a function of time t. Assume the object started by being compressed 16 cm from the equilibrium position (where y = 0), and released. Note: the equilibrium position is defined here as that location of the mass at rest when it is freely hung from the spring, not...
