A 30.0-g goldfinch lands on a slender branch, where it oscillates up and down with simple harmonic motion of amplitude 0.0335 m and period 1.65 s.
(a) What is the maximum acceleration of the finch? Express your answer as a fraction of the acceleration of gravity, g.
(b) What is the maximum speed of the goldfinch?
(c) At the time when the goldfinch experiences its maximum acceleration, is its speed a maximum or a minimum? Explain. |
