Name Period Date Vectors: Worksheet 3 Vector Addition Computational Method For each problem, compute the missing side(s) and/or angle. c b c c b b a a a 1. a = 20. m, b = 15 m 2. c = 5.0 m , 35 s 3. a = 10.0 m, c = 12.5 m a b c a b c 4. a = 36 m , b = 25 m s s 5. c = 45 m, 25 Vectors: Worksheet 3 Page 2 For each question: Begin by sketching a vector diagram. Computationally determine the resultants. Answer with both a magnitude and a direction. 6. You walk 100. m South, then 50. m East. What is your displacement? 7. A plane is traveling at 75 m/s West, when a 10. m/s wind begins to blow North. What is the resultant velocity of the airplane? 8. You walk 20. blocks North, then 10. blocks East, then 18 blocks South. What is your displacement? 9. A certain river has a current that flows at 2.0 m/s West. If you point your boat, which can move at 5.0 m/s, directly across the stream to the North, what is your resultant velocity?
