After 11'30, the key will be posted under Announcement. No more submission. #1 Avector B = Bxi + Byj. when added to the vector C = 3.0i + 4.0], yields a resultant vector A that is in the negative 3.!- direction and has a magnitude which is twice that of C. Find {a} BI and B... {b} the magnitude of B, {c} the angle between B and C. #2 John had a good long walk on Sunday morning with his dog. He started from his home {0) walking 1.2 mile east, then walked 1.5 miles 30 degree N of E. followed by another walk of 2.0 miles 45 degrees of 5 of W to reach point A. What is his position with respect to his home {vector 0A] ? You can solve this problem by either using vector graphic method [dene 1cm represent 0.5 mile on graph, add three vectors} or unit vector method {for example, R1=1.2i. R2=1.5cos30i+1.55in50j, etc...)
