Question

Shweta runs around a circular race track of radius 60 m with a constant speed of 12 m/s. Find her angular speed.​

Answer 1

$\huge \mathfrak \pink{answer}$

Radius of lap = 100m

Circumference =2πR=200π=628m

time taken to cover one lap = 62.8s

Hence average speed = 62.8628 =10ms −1

Average velocity = 0 as the inital and final positions are same (after completing a lap) (displacement = 0)
