50 At time zero, a particle is at x = 4.0 m

50 At time zero, a particle is at x = 4.0 m and y = 3.0 m and has velocity = (2.0 m/s)i + (-9.0 m/s). The acceleration of the particle is constant and is given by a = (4.0 m/s) + (3.0 m/s). (a) Find the velocity at t = 2.0 s. (b) Express the position vector at t = 4.0 s in terms of i and . In addition, give the magnitude and di- rection of the position vector at this time.
