9.2.An airplane propeller is rotating at 1900 rpm 1rev>min2.(a) Compute the propeller's angular velocity in rad>s. (b) How many seconds does it take for the propeller to turn through 35'"? 9.11..The rotating blade of a blender turns with constant angu-Iar acceleration 1.50 rad>32. (a) How much time does it take to reach an angular velocity of 36.0 rad>s, starting from rest? (b) Through how many revolutions does the blade turn in this time interval? 9.25..Centrifuge. An advertisement claims that a centrifuge takes up only 0.127 m of bench space but can produce a radial ac-celeration of 30009 at 5000 rev>min. Calculate the required radius of the centrifuge. Is the claim realistic? 9.31.A uniform bar has two small balls glued to its ends. The bar is 2.00 m long and has mass 4.00 kg, while the balls each have mass 0.300 kg and can be treated as point masses. Find the moment of inertia of this combination about an axis (a) perpendicular to the bar through its center; (b) perpendicular to the bar through one of the balls A thin, rectangular sheet of metal has mass M and sides of length a and b. Use the parallel-axis theorem to calculate the moment of inertia of the sheet for an axis that is perpendicular to the plane of the sheet and that passes through one corner of the sheet
