## Question:

A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 4 m, y = 3 m, and has velocity v = 2 m/s i - 9 m/s j. The acceleration is given by the vector a = 4 m/s^{2} i + 3 m/s^{2} j.

(a) Find the velocity vector at t = 2 s.

(b) Find the position vector at t = 4 s. Give the magnitude and direction of the position vector.
