Question

What is the x component that of a vector that is defined 2.5m at 64 degree?

A) -2.2m
B) 1.1m
C) 2.2m
D) -1.1m

Answer 1

Step-by-step explanation:

This is a displacement vector since it is given in terms of a distance (meters, to be specific). The way you find the x-component is:

`V_x=Vcos\theta` which means you multiply the magnitude (length) of the vector times the cos of the direction (the angle):

`V_x=2.5cos(64)` to get

1.1 m, choice B.
