The horizontal coordinates of a frisbee in a strong wind

Question

Compute all parts of given question:

Question: The horizontal coordinates of a Frisbee in a strong wind are given by x = -12 t +4t² and y = 10 t -3t² where x and y are in meters, and t is in seconds.

Part A: What is the acceleration of the Frisbee?

Part B: What is the magnitude of the velocity at t = 2.0 s, accurate to the nearest m/s?

I need help to determine the acceleration of the Frisbee.
