A cyclist moving on a circular track of radius 100m to complete one revolution in4min. find average speed and velocity |
|
Answer» The TOTAL LENGTH of the circular track = 2πr = 2π(100) = 200π metres Total time taken = 4 MINUTES = 240 seconds Average speed = distance/time = 200π/240 = 5π/6 m/s = 2.6 m/s Average velocity = displacement/time = 0/240 = 0 m/s Therefore the average speed is 2.6 m/s and average velocity is 0 m/s. Hope it helps!! |
