In the diagram, the dashed lines are parallel to the x axis. The magnitudes of the vectors are A = 8.8, B = 6.8, C = 13.5, D = 21.9, and F = 21.9. The angles, in degrees, are θA = 30.0, θB = 53.0, θC = 60.0, θD = 37.0, and θF = 30.0. In this problem, you will be asked to calculate the value of a variety of scalar (dot) products.
a) What is A • C?
b) What is A • F?
c) What is D • C?
d) What is A • (F + 2C)?
e) What is i • B?
f) What is j • B?
g) What is (3i - j) • B?
h) What is (B/B) • B?
