Question

A particle excuting circularmotion and horizontal circular path of radius 12cm it complete 3 revolution per second .caculate its angular velocity and liner velocity

Answer 1

• Given :

=> Radius r = 12 cm = 0.12 m

=> Frequency f = 3 rev/s

• To Find :

=> Angular velocity w = ?

=> Linear velocity v = ?

• Formula :

=> Angular velocity w = 2*pi*f

=> Linear velocity v = w*r

• Calculation :

=> w = 2*3.14*3 = 18.84 rad/s

=> v = 18.84*0.12 = 2.26 m/s

• Answer :

=> Angular velocity = 18.84 rad/s

=> Linear velocity = 2.26 m/s
