A car travelling along a road is making a turn where the radius of curvature is r = 2t²m where t rad is in seconds. An observer at the center of the curve focuses on the car, turning at a rate of 0.5tdd where t is in seconds. Find the magnitude and equation of the velocity and acceleration when 2 seconds have passed.
