Have your responses handy as you go through the rubrics to see how you did! The tension will be lower at point B than it is at the bottom as there is a component of gravity helping the tension in the centripetal direction (as opposed to gravity acting centrifugally at point A): FcA = FcB = mv2/R TA mg = TB + mg sin 30 = mv2/R TB = TA mg(1 + sin 30) (ii) Constant tension will result in a much higher speed at point B as the tension will be locked in at TA above. What is the net displacement of the car? modify or replace with new ones.
