if a cyclist takes one minute to comple half revolution on a circular path 120 m radius.what is the average velocity?
If cyclist takes two minute to complete half revolution on circular path120m radius what is the average speed?
Since average velocity=total distance/total time
Distance covered by cyclist,s=2r
Average velocity=s/t=2r/t=2(120)/60
= 4 m/s
pi*(radius)/(60 seconds) = 6.28 m/s
That is not very fast for a cyclist. Sprinters can run over 10 m/s.
To find the average velocity of the cyclist, we need to know the distance traveled and the time taken.
The distance traveled can be calculated by finding the circumference of the circular path, which is given by the formula 2 * π * radius. In this case, the radius is 120 m, so the distance traveled is:
Distance = 2 * π * 120 = 240 * π ≈ 753.98 m
The time taken by the cyclist is given as 1 minute.
So, average velocity = Distance / Time = 753.98 m / 1 min = 753.98 m/min
Therefore, the average velocity of the cyclist is approximately 753.98 meters per minute.
