Question

Rohith completes a semicircular path of radius 12 in 10 seconds calculate average speed and average velocity in m/s

Answer 1

Explanation:

length AB = 2R  arc AB = (1/2) circumference = πR  average speed = {(arc AB) / (10)} = (πR / 10)  average velocity = {(length AB) / (10)} = (2R / 10)Read more on Sarthaks.com - https://www.sarthaks.com/318546/rohit-completes-semicircular-radius-seconds-calculate-average-speed-average-velocity
