Answer»

ANSWER:

Horizontal component = √a² + b²

Step-by-step explanation:

If u=ai+bj+ck with i,J,k are in east,north and vertical directions. the horizontal component of the velocity is  

1) a

2)b

3)(a²+b²)^1/2

4)(b²+c²)^1/2

Here east & north are horizontal components  

so i & j are horizontal

while k is vertical

as i & j are North & East so at angle of 90°

so Horizontal component = √a² + b²

= (a² + b²)^(1/2)
