Answer 1

Explanation

• The Velocity " v " of the man is in the direction, say, from East to West. The velocity "u" of the boy is in the direction, say, from South to North.

• As the velocities are both perpendicular to each other, we apply the vector sum.

Relative velocity = v - u

Magnitude = sqrt[ u^2 + v^2 ]

= sqrt (5^2 +10^2)

= 5 × sqrt(5) m/s.

• It's direction is South West as v is towards West and (-u) is towards South.
