A 1240 kg 1240 kg car has just passed a diner. The closest the car came to the diner was R = 20.5 m R=20.5 m , but the car has driven another x = 30.7 m x=30.7 m in the 2.25 s 2.25 s elapsed since then. If the car travels at constant speed, what is the current magnitude L L of the angular momentum of the car about the diner?
