Answer 2

Answer:

3m towards negative direction

Explanation:

resultant vector of two vectors a and b is

square root of (a square+b square+2abcostheta),where theta is the angle between a and b

here as the vectors are in horizontally opposite direction,theta is 180degree

so square root of (5 square+8 square+2*5*8*cos180)

square root of (25+64+80*-1)

square root of(89-80)

square root of 9=3

so,3m towards negative direction
