Question

three vectos are shown in fig. 3-32. their magnitudes are given in arbitrary units. Determine the sum of the three vectors. Give the resultant in terms of (a) components, (b) magnitude and angle with the x axis.

(3-32 --the figure has three rays all starting at the origin. Ray A = 44.0 and is 28degress from the x axis in quodrent 1. Ray B=26.5 and is 56degress from the x axis in quodrent 2. Ray C=31.0 and is on the y axis between quodrent 3 and 4.)

Answer 1

break up all three vectors into x,y components. then add the x's, and the y's.

That is the resultant vector.

Answer 2

a)4
b)4
C)3

Answer 3

A0
b)
