13. While riding in a car, heading East, you hold an accelerometer in your hand. The accelerometer is made from a bead hanging from a string, attached to a protractor which can measure the angle as shown. [3 marks] a. Describe what happens to the bead when the vehicle is at rest. b. Describe what happens to the bead when the vehicle is accelerated toward the East. 0706050 vertical bead c. The bead is at an angle of 11° from the vertical. Calculate the magnitude of the car's acceleration. 40506070
