An object, oscillating harmonically in the x-coordinate, follows a trajectory described by the following equation: x(t) = 3.83 cm *sin(4.18 s-1 *t).
(a) Where is the object when t=37.3 s?
(b) What is its speed at t=37.3 s?
(c) What is the maximum speed attained by the object?
(d) Where are the turning points for this oscillator?
(e) In which 10% of the distance between the turning points does the oscillator spend the least amount of time?
