Question

a
has magnitude 12 m and B has magnitude 8 meter the x component of a + b​

Answer 1

Answer:

In the diagram vector A has magnitude 12 m and vector B has magnitude 8 m. The x component of vector a + vector b is about

A) 5.5m      B) 7.6m      C) 12m      D) 14m

Explanation:

Answer 2

Answer:

c) 12m

explain

x component of vector A = Acos45

x component of vector B = Bcos60

x component of A+B = Acos45 + Bcos60

= 12(1/√2) + 8(1/2)

= 8.4 + 4

= 12.4m

near to 12.4m is 12m so the correct answer is c) 12m
