An Oil Tanker Heading Due West, Straight into a Strong

question 56

Multiple Choice

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, which is 100 million kg. If the wind blows at the same strength for 5 minutes, then how much has the wind changed the tanker's speed?

• A) 1.2 m/s
• B) 1.08 m/s
• C) 0.018 m/s
• D) 0.18 m/s
