The 2.4-kg particle moves in the horizontal x-y plane and has the velocity shown at time t = 0. If the force F = 2 + 3t²/4 newtons, where t is time in seconds, is applied to the particle in the y-direction beginning at time t = 0, determine the velocity v of the particle 4 seconds after F is applied and specify the corresponding angle θ measured counterclockwise from the x-axis to the direction of the velocity.
