(c) If r = 10 m and v = 12 m/s, we obtain F B = – 2.3 × 10 3 N = – 2.3 kN, or | F B | = 2.3 kN. (d) The minus sign indicates that G F B points downward. 50. The situation is somewhat similar to that shown in the “loop-the-loop” example done in the textbook (see Figure 6-10) except that, instead of a downward normal force, we are dealing with the force of the boom G F B on the car – which is capable of pointing any direction. We will assume it to be upward as we apply Newton’s second law to the car (of
