The velocity of a 5.00 kg particle is given by (2.00t î+ 7.00t²) m/s, with time t in seconds. At the instant the net force on the particle has a magnitude of 45.0 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? (a) Number i (b) Number i = Units Units
