1. An object of mass m = 1 kg oscillates with position x(t) = 10 cos (2πt - л/6) meters. a) What is the frequency o and the period T? b) What is the velocity v(t)? c) At what times is the object going through the equilibrium position x = 0 ? d) At what times is the object at maximum distance from the equilibrium point? For e) and f), do not calculate, refer to your results from c) and d). e) At what times is the speed maximum? f) At what times is the acceleration maximum?
