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)

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
