An electric turntable 0.700 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.270 rev/s . The angular acceleration is 0.905 rev/s2 .

Compute the angular velocity after a time of 0.191 s .

Through how many revolutions has the blade turned in this time interval?

What is the tangential speed of a point on the tip of the blade at time t = 0.191 s ?

What is the magnitude of the resultant acceleration of a point on the tip of the blade at time t = 0.191 s ?
