A car travelling along a road is making a turn where the radius of curvature is r = 2t? m where t is in seconds. An observer at the center of the curve focuses on the car, turning at a rate of 0.5t where t is in seconds. Find the magnitude and equation of the velocity and acceleration when 2 seconds have passed m m 11.31-; 20.40
