When the car is stopped at a light, the crystal hangs vertically. When the light turns green, the driver accelerates and notices the crystal makes an angle of 0 = 13 degrees with respect to the vertical. theexpertta.com d 25% Part (a) Please select the correct free body diagram, using an inertial coordinate system fixed to the road, given F is the force due to gravity, Fr is the tension in the string, Fa is the centrifugal acceleration and Fy is the normal force.
