Question

1) The magnitude of vector A is 16, that of vector B is 22 and that of vector C is 44. Vector A pointing north of west with an angle of 32^o above the -x axis, vector B is pointing north of east with an angle of 19^o clockwise (right) of the +y axis and vector C is pointing south of west with an angle of 58^o below the -x axis.

a) draw vectors A, B and C in the x-y axis set

b) find the x and y components of vectors A, B and C

c) find the magnitude and direction of the vector sum D = A + B + C

2) The magnitude of vector A is 254, that of vector B is 220 and that of vector C is 144. Vector A pointing south of west with an angle of 32^o below the -x axis, vector B is pointing north of west with an angle of 12^o above the -x axis and vector C is pointing south of east with an angle of 58^o counterclockwise (right) from the -y axis.

a) draw vectors A, B and C in the x-y axis set

b) find the x and y components of vectors A, B and C

c) find the magnitude and direction of the vector sum D = A + B + C
