Question

1.- An object moves 20m 30° east of south, and then 10m 40° north
of west. Find the net displacement of the object and give its
heading. Use only the law of cosines and trigonometric functions.
A=3.5 î - 8.2ĵ is substracted from a second
that has a magnitude of 9.2 in a direction of 47°
2.- A first vector
vector B
measured clockwise from the negative x axis. Calculate the
magnitude and direction of the resulting vector.
