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. Ā This wind force is pointing backwards, to the east. The tanker's mass is 100,000 metric tons, which is 100 million kg. If the wind blows at the sameĀ strength for 5 minutes, then how much has the wind changed the tanker's speed?

A. 0.18 m/s
B. 0.018 m/s
C. 1.2 m/s
D. 1.08 m/s
