Expert Answer

Step 1

Consider the point from which the vector begins to be the origin. Now, consider the components vertically upward and horizontally rightward from the origin to be positive, and those vertically downward and horizontally leftward from it to be negative. 

Step 2

(a) In this part, the components of the velocity vector along horizontal and vertical axes, respectively are:

.(1)
V cos=30 m/s
vvsin 40 m/s
