The acceleration of a particle moving only on a horizontal xy plane is given by a = 5tî + 6tj, where a is in meters per second-squared and t is in seconds. At t = 0, the position vector 7 = (28.0m)i + (47.0m) locates the paticle, which then has the velocity vector = (4.20m/s)i + (2.10m/s)j. At t = 5.90s, what are (a) its position vector in unit-vector notation and (b) the angle between its direction of travel and the positive direction of the x axis?
