Question: (a) In unit-vector notation, what is r = a 6 + c if a = 5.0i + 4.0i 6.0k, b = 2.0i

(a) In unit-vector notation, what is r = a – 6 + c if a = 5.0i + 4.0i – 6.0k, b = – 2.0i + 2.0j + 3.0k, and c =

4.0i + 3.0j + 2.0k

(b) Calculate the angle between r and the positive z axis.

(c) What is the component of d along the direction of b?

(d) What is the component of d perpendicular to the direction of b but in the r plane of a d and b?
