A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABCis 214 m, and the car completes the turn in 0 s. An x y coordinate system is shown in the figure. Three points A, B, and C are shown on the graph. These points are joined by a dotted curve. Point A is on the negative y-axis, point C is on the positive x-axis, while point B is in the fourth quadrant IV at an angle of −35° with the x-axis. From point A the curve initially moves rightward along a circular path, curves upward to cross B and then meets C. An arrow indicating the velocity at point A points horizontally and to the right. An arrow indicating the velocity at point C points vertically upward. What is the acceleration when the car is at Blocated at an angle of 35.0°? Express your answer in terms of the unit vectors î and ĵ. Determine the car's average speed. Determine its average acceleration during the 34.0-s interval.
