Question

Vector A has a magnitude of 18 (in some unspecified units) and makes an angle of 25 with the x axis, and a vector B has a length of 24 and makes an angle of 70 with the x axis. Find the components of the vector C in the following: 
(a) C = A + B
Cx =
Cy =
(b) C = A - B
Cx=
Cy=

drwls · Answer

The x component of A is 18 cos25
The y component of A is 18 sin25
The x component of B is 24 cos70
The y component of B is 24 sin70

Compute the numbers using trig functions and then compute C by adding or subtracting components.
