3. A car initially travelingeastward turns north bytraveling in a circularpath at uniform speedas shown in Figure P6.3.The length of the arcABC is 235 m, and theyV35.0°Ccar completes the turnin 36.0 s. (a) What is thcВacceleration when the carAis at B located at an angleof 35.0°? Express yourFigure P6.3answer in terms of theunit vectors i and j. Determine (b) the car's average speedand (c) its average acceleration during the 36.0-s interval. The length of the arc is 250 meters, and the time to turn is 37 seconds. Calculatethe x-component of the acceleration (in m/s2) at point B, where the angle is 69°.Calculate the average speed in m/s. The numbers:• Length of the arc: 219 meters• Time to turn: 49 secondsNow calculate the y-component of the average acceleration. The book itself isunclear whether what's asked for is the average of the vector, the magnitude ofthe vector average, or the average of the magnitude. But the answer at the backof the book indicates the vector.• Length of the arc: 227 meters• Time to turn: 46 seconds

SOlution: given that lenght of arc L= 235 m angle = 35 degree t = 36 s
