3. [-/3 Points] DETAILS A car is 1.7 km west of a traffic light at t = 0 and 5.2 km east of the light at t = 5.7 min. Assume the origin of the coordinate system is the light and the positive x-direction is eastward. (Express your answers in vector form.) (a) What are the car's position vectors (in km) at these two times? x(t = 0) = km x(t = 5.7 min) = km (b) What is the car's displacement (in km) between 0 min and 5.7 min? Ax = km T Additional Materials Reading
