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?

change tangentialacceleration to angular acceleration.

angular acceleration= tangential acc/radius

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