The Horizontal Coordinates of a Frisbee™ in a Strong Wind

question 38

Short Answer

The horizontal coordinates of a Frisbee™ 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?
