A 30.0-g goldfinch lands on a slender branch, where it oscillates up and down with simple harmonic motion of amplitude 3.50*10^-2m and period 1.50s .
Part A What is the maximum acceleration of the finch? (m/s^2)
Part B Express your answer as a fraction of the acceleration of gravity, g .
Part C What is the maximum speed of the goldfinch?
Part D At the time when the goldfinch experiences its maximum acceleration, is its speed a maximum or a minimum?
