Question

has a magnitude of8.00 m and makes an angle of 45.00 with thepositive x

axis. VectorB

also has a magnitudeof 8.00 m and is directed along the negative x axis.

Using graphicalmethods, find a) the vector sum A B

?? ??

+ and b) the vector

differenceA B

?? ??

. (Remember A B

?? ??

+ and AB

?? ??

are resultant vectors and you should

report their directionby giving their angles from the positive x axis.You also need to

2)Three vectors are oriented as shown in figure,where 0 . 20 = A

units, 0 . 40 = B

units, and

0 . 30 =C

units. Find a) the x and y components of the resultant vectorand

b) the magnitude and direction of the resultantvector.

(Answer: a) x=49.5units, y=27.1units; b) 56.4 units at 28.7 from the positive xaxis.)
