7. an oil tanker heading due west, straight into a strong
wind, reaches a speed of 5 m/s and then shuts down
its engines to drift. the forward-facing flat surfaces
of the tanker catch a total of 60,000 n of force from
the wind. this wind force is pointing backwards, to
the east. the tanker's mass is 100,000 metric tons. if
the wind blows at the same strength for 5 minutes,
then how much has the wind changed the tanker's
speed? (5 points)
