The speedometer on your car reads a steady 35 mph. Could you be accelerating? Explain. Choose the correct answer and explanation. O A. Yes. If the car is moving along a curved path (K0), then a = K v #0 and a = a + aN*0. OB. No. If the car is moving along a curved path (K=0), then a = K |v| = 0 and a=a+T+aN=0. O C. No. The car is not accelerating if the speed is constant. O D. Yes. On a curved path, the velocity always changes in magnitude, but it may or may not change in direction, which means that the acceleration of an object moving on a curved path can never be zero.
