Two-Dimensional Motion: the Horizontal Coordinates of a Frisbee^TM in a Strong

question 37

Essay

Two-dimensional motion: The horizontal coordinates of a Frisbee^TM in a strong wind are given by x = -12t + 4t² and y = 10t - 3t², where x and y are in meters, and t is in seconds.
(a) What is the acceleration of the Frisbee? Give a magnitude and a direction, measuring angles from the positive x direction.
(b) What is the magnitude of the velocity at t = 2.0 s, accurate to the nearest m/s?
