The velocity of a 5.00 kg particle is given by 7 = (6.00tî + 5.00t² ĵ) m/s, with time t in seconds. At the instant the net force on the particle has a magnitude of 44.0 N, what are the direction (relative to the positive direction of the x-axis) of (a) the net force and (b) the particle's direction of travel?
