The diagram shows a top-down view of a 1000 kg car on a circular racetrack. At the moment shown the car is moving to the right with speed 30 m/s and slowing down with a tangential acceleration of magnitude 5 m/s^2. The radius of curvature of the curve is 50 m. a. Find the radial acceleration, both magnitude and direction, of the car. b. What is the direction of the tangential acceleration of the car? c. Find the magnitude of the overall acceleration of the car. d. Find the direction, CCW from the x-axis, of the acceleration, and draw the acceleration vector on the diagram.
