where
I is the current
Q is the charge
is the time interval
For the lightning bolt in our problem, Q=6.0 C and
, so the average current during the event is
where
I is the current
Q is the charge

Explanation:
It is given that,
Mass of Madeleine,
Initial speed of Madeleine, (due east)
Final speed of Madeleine, (due west)
Mass of Buffy,
Final speed of Buffy, (due east)
Let is the Buffy's velocity just before the collision. Using the conservation of linear momentum as :
So, the initial speed of the Buffy just before the collision is 7.13 m/s and it is moving due west. Hence, this is the required solution.
