Homework should be written
out neatly on a separate sheet of paper. Explain your reasoning.
1) Find the sum of the two
vectors shown in the diagram below. The red vector has a magnitude 60 m and is
at a 55 degree angle to the y-axis. The green vector has a magnitude 85 m and
is at a 65 degree angle to the –x-axis. Show your work.
2) Find the sum of the three
vectors shown in the diagram below. The red vector has a magnitude 28 m and is
at a 31 degree angle to the y-axis. The green vector has a magnitude 58 m and
is at a 28 degree angle to the –x-axis. The blue vector has a magnitude 61 m
and is at a 57 degree angle to the –x-axis. Show your work.
3) A woman drives 3 km north,
then 12 km to the northwest, and finally 5 km south-southwest. How far has she
