A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 7.0 m, y = 7.0 m, and has velocity v = 3.0 m/s + -3.0 m/s . The acceleration is given by the vector a = 2.0 m/s2 + 5 m/s2 .
(a) Find the velocity vector at t = 10.0 s.
(b) Find the position vector at t = 1.0 s.
(c) Give the magnitude and direction of the position vector in part (b).
