The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
What is Average Velocity?
Average velocity is simply the displacement of a particle or object over time. It is the rate of change of position of an object with respect to time.
It is expressed as;
Velocity = displacement / time
It can also be expressed as;
Velocity = circumference / time = 2πr / t
Given the data in the question;
- Radius of the track r = 500m
- Time elapsed t = 50s
- Average velocity V = ?
To determine the average velocity, we substitute our values into the expression above.
V = 2πr / t
V = ( 2 × 3.14 × 500m ) / 50s
V = 3140m / 50s
V = 62.8m/s
The average velocity of the race car around the circular track in the given time is 62.8m/s.
Hence, option D) None of the above is the correct.
