Question

A cyclist goes around a circular track ones in every 2mins if the radius is 105 calculate his speed.(circular motion)​

Answer 1

given :-

given :- Radius , r = 105

given :- Radius , r = 105 time t = 2min

given :- Radius , r = 105 time t = 2min = 120 second

given :- Radius , r = 105 time t = 2min = 120 second we know also

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105⇒ 660 m

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105⇒ 660 m∴ speed = distance / time

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105⇒ 660 m∴ speed = distance / time ⇒660 m/ 120

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105⇒ 660 m∴ speed = distance / time ⇒660 m/ 120⇒5·5m/s

given :- Radius , r = 105 time t = 2min = 120 second we know also circumference or distance of circle = 2πr ⇒2×22/7×105⇒ 660 m∴ speed = distance / time ⇒660 m/ 120⇒5·5m/s
