Question

A railroad engine moves forward along a straight section of track for a distance of 100 m due west at a constant speed of 5 m/sec. It then reverses its direction and travels 40 m due east at a constant speed of 4 m/sec. The time required for it to slow down and reverse is very short due to the small speeds. What is the average velocity of the engine?

Step 1

Given: - Distance traveled west: 100 m - Speed west: 5 m/s - Distance traveled east: 40 m - Speed east: 4 m/s Time taken to travel west = Distance / Speed = 100 m / 5 m/s = 20 seconds Time taken to travel east = Distance / Speed = 40 m / 4 m/s = 10 seconds Total Show more…
