Review Multiple Concept Example 9 before beginning this problem. As an aid in visualizing the concepts in this problem, consult Concept Simulation 1.1. A football player runs the pattern given in the drawing by the three displacement vectors A, B, and &. The magnitudes of these vectors are A = 4.00 m, B = 14.0 m, and C = 18.0 m. Using the component method, find the (a) magnitude and (b)direction @) of the resultant vector A + B + . Take @ to be a positive angle. 90.0 35.0 A Start A +B+C (a) Number i Units (b) Number UnitsConcept Simulation 2.3 offers a useful review of the concepts that lie at the heart of this problem. Two rockets are ying in the same direction and are side by side at the instant their retrorockets re. Rocket A has an initial velocity of +5300 m/s, while rocket B has an initial velocity of +9100 m/s. After a time t both rockets are again side by side, the displacement of each being zero. The acceleration of rocket A is -19 m/sZ. What is the acceleration of rocket B? Number n Units V
