Given a velocity of 4m/s[E] and a second velocity of magnitude 6m/s
(this is all that is given)

Find the maximum and minimum values for the final velocity.

• Physics -

The vector sum has a minimum magnitude (speed) of 2 m/s (when the two vectors are in opposite directions) and a maximum of 12 m/s (when they are aligned).
