Besar Resultan Vektor a+b

By Ahlif ID Post a Comment

Vektor a = 4î + 4ĵ dan vektor b = 2î + 4ĵ. Besarnya vektor resultan a + b adalah …

A. 8 satuan

B. 10 satuan

C. 28 satuan

D. 36 satuan

E. 64 satuan

 

PEMBAHASAN

Diketahui

ax = 4 , ay = 4

bx = 2, by = 4

Ditanya |a+b| = ….?

Jawab

|a+b| = √(ax + bx)2 + (ay + by)2

|a+b| = √(4+2)2 + (4+4)2

|a+b| = √62 + 82

|a+b| = √36 + 64

|a+b| = √100

|a+b| = 10 satuan (B)
