The acceleration of a particle moving only on a horizontal xy plane is given by, where is in meters per second squared and t is in seconds. At t 0, the position vector locates the particle, which then has the velocity vector. At t 4.00 s, 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
