Use the component method to add the vectors A
and B shown in Figure P3.9. Both vectors have mag-
nitudes of 3.00 m and vector A makes an angle of
0 = 30.0° with the x axis. Express the resultant Á + B in
unit-vector notation.
In the previous problem, a vector with magnitude 30 points 57 degrees north of east.
Ruth sets out to visit her friend Ward, who lives 60 mimi north and 100 mimi east of her. She starts by driving east, but after 20 mimi she comes to a detour that takes her 15 mimi south before going east again. She then drives east for 8 mimi and runs out of gas, so Ward flies there in his small plane to get her.
1. What is Ward's displacement vector? Give your answer in component form, using a coordinate system in which the y-axis points north.
2.What is the magnitude of Ward's displacement vector?
3. What is the direction of Ward's displacement vector?
