A particle moves in the xy plane with constant acceleration. Attime zero, the particle is at x = 3.0 m, y = 6.0 m, and hasvelocity v = 8.0 m/s i + 7.0 m/s j. The acceleration is given bythe vector a = 10.0 m/s2 i + 3 m/s2 j.
(a) Find the velocity vector at t = 7.0 s.
(b) Find the position vector at t = 5.0 s.
(c) Give the magnitude and direction of the position vector in part(b).
