Average velocity = displacement/ time
= diameter/ 20= 140/20= 7 m/ sec
Average speed = distance / time
= (circumference of semi circle )/ time
= (22/7*70)/20= 11 m/ sec
= diameter/ 20= 140/20= 7 m/ sec
Average speed = distance / time
= (circumference of semi circle )/ time
= (22/7*70)/20= 11 m/ sec
