A cylinder with a diameter of 23 cm rolls with an angular speed of 0.30 rad/s on a level surface. If the cylinder experiences a uniform tangential acceleration of 0.022 m/s2 without slipping until its angular speed is 1.01 rad/s, through how many complete revolutions does the cylinder rotate during the time it accelerates?

  • physics -

    change tangentialacceleration to angular acceleration.

    angular acceleration= tangential acc/radius


    Wf^2=Wi^2+2*angacceleration*revolutions*2PI
