Dr. Sheldon Cooper and Penny are on the way to the Comic Book Store to buy a gift for Leonard. Penny is driving her car at a speed of 30.0 m/s along a straight portion of the expressway of Pasadena when she applies the brakes at point A and reduces her speed at a uniform rate until her speed at C becomes 18.00 m/s The curved section B-C is 62.0 m long with a constant radius of curvature of 75.0 m. 80 m B 75 m 62 m D 1. Which of the following statements are TRUE regarding the motion of Penny's car along the curved portion of the path B-C? 1. Its acceleration is tangent to its path. II. Its velocity is tangent to its path. III. Its normal acceleration is directed towards point D.
