A truck on an exit ramp is moving in such a way that, at the instant shown, and ϕ = 13°. Let the distance between points A and B be dAB = 4 m. If, at this instant, the truck is turning clockwise, θ = 59°, aBx = 6.3 m/s2, and aBy = −2.6 m/s2, determine the angular velocity and angular acceleration of the truck.
