A 2.25 kg pumpkin oscillates from a vertically hanging light spring once every 0.85 s. A) Find the equation giving the pumpkin's position ( upward) as a function of time , assuming it started by being compressed 17 cm from the equilibrium position (where = 0), and released.

y(t)=(.17m) x cos ((2pi)(t))/(.85 s)
B) How long will it take to get to the equilibrium position for the first time? (in s)
C) What will be the pumpkin's maximum speed? (in m/s)
D) What will be its maximum acceleration, and where will that first be attained? (in m/s^2)
