Question

Quizplus · Accepted Answer

The magnitude of a vector can be found using the Pythagorean theorem: 
|v| = sqrt((v_x)^2 + (v_y)^2) 
Plugging in the given components: 
|11ea6ebb_72c7_fc31_9d78_c7ced595f6f6_TB6213_11| = sqrt((12 m)^2 + (5.0 m)^2) 
= sqrt(144 m^2 + 25 m^2) 
= sqrt(169 m^2) 
= 13 m

A Vector Has Components Ax = 12 M and Ay
