What is the average velocity of a fighter jet that flies 3 km west and then 2 km east in 8 minutes?
The jet's average velocity is 7.69 km/hr due east.
Explanation:
The average velocity of the fighter jet can be determined by calculating the rate of change of displacement over time. In this scenario, the jet initially moves 3 km west and then 2 km east, resulting in a net displacement of 1 km due east. The total time taken for these movements is 8 minutes.
Given Parameters:
- Displacement due west = 3 km
- Displacement due east = 2 km
- Time taken = 8 minutes
Unknown:
Average velocity = ?
Solution:
To calculate the average velocity, we need to convert the time from minutes to hours:
- 1 hour = 60 minutes
- 8 minutes = 8/60 hours = 0.13 hours
Therefore, the average velocity can be calculated using the formula: Velocity = Displacement/Time
Average velocity = 1 km / 0.13 hr = 7.69 km/hr due east
