```							Dear student  consider these velocities on an x-y plane with vectors i and j (+i = East, -i = West, +j = North, -j = South): initial velocity = 50j. final velocity = -50i. change in velocity (Δv) = final velocity – initial velocity = -50i -50j  and  -i direction (west) and -j direction (south), so the total change in velocity will be pointing towards the southwest.|Δv| = √[(-50)² + (-50)²] |Δv| = 70.7 km/hHope this helps Good Luck
