An electric turntable 0.720 m in diameter is rotating about a fixed axis with an initial angular velocity of 0.290 rev/s. The angular acceleration is 0.920 rev/s2.
a) Compute the angular velocity after a time of 0.193 s . Express your answer in revolutions per second.
b) Through how many revolutions has the blade turned in this time interval?
Express your answer in revolutions.
c) What is the tangential speed of a point on the tip of the blade at time t = 0.193 s ?
Express your answer in meters per second.
d) What is the magnitude of the resultant acceleration of a point on the tip of the blade at time t = 0.193 s ?
Express your answer in meters per second squared.
