Here are three displacements, each in meter; d1 = 4.0i + 5.0j – 6.0k, d2 = – 1.0i + 2.0j + 3.0k, and d3 = 4.0i + 3.0j + 2.0k.

(a) What is r = d1 – d2 + d3

(b) What is the angle between r and the positive z axis?

(c) What is the component of d1 along the direction of d2?

(d) What is the component of d1 that is perpendicular to the direction of d2 and in the plane of d1 and d2?
