"What is the magnitude of acceleration after 1.5 seconds of a sphere thrown upward from a height of 13 meters at 20 m/s^2?"

Choices

a) 5.3 m/s^2

b) 9.8 m/s^2

c) 15 m/s^2

d) 32 m/s^2

e) 390 m/s^2

I realize these are quite obvious answer choices, and the answer is most likely D, but I don't know how to get it. I only have the "four kinematics" equations to work with, but I think there are other equations I can use for this. How does the height of 13m effect my answer, if it indeed does.
