a body starts from rest and completes 6 revolutions in 4 seconds .find the number of revolutions it makes in 8 seconds .and its angular velocity after 10 seconds
 

Given ω0 =0, ω = 6×2π4=3π rad/sNumber of revolution in 1 second = 64=32therfore is 8 s number ofrevolution =32×8=12 revolutionω=ω0+αt3π=0+ α×4α=3π4rad/s2Angular velocity after 10 sω=0+3π4×4ω=3π4x10 =7.5πrad/sRegardsVijaya
