Abody makes six complete revolution in 4.0sec if it makes in a circle of raduis 25.0cm calculate th linear velocity

The distance around a circle is (2 · π · radius) .

Length of one revolution = (2 · π · 25 cm)

One revolution = 157.1 cm

One revolution = 1.571 meter

Six revolutions = (6 · 1.571 meter) = 9.425 meters

Speed = (distance covered) / (time to cover the distance)

Speed = (9.425 meters) / (4.0 sec)

Speed = 2.36 m/s
