*50. D Multiple-Concept Example 7 ex- plores the approach taken in problems such as this one. The blades of a ceiling fan have a radius of 0.380 m and are rotating about a fixed axis with an angular velocity of +1.50 rad/s. When the switch on the fan is turned to a higher speed, the blades acquire an angular acceleration of +2.00 rad/s². After 0.500 s has elapsed since the switch was reset, what is (a) the total acceleration (in m/s²) of a point on the tip of a blade and (b) the angle ø between the total acceleration a and the centripetal acceleration a? (See Figure 8.12b.)

While placing a compact disc into a CD player, you notice a small chip on its edge. You attempt to play the CD anyway by placing the CD into the player's deck with the chip at 0o = 12.6° as measured from the +x-axis. The CD begins to rotate with angular acceleration a = 2.31 rad/s². If the CD has been spinning for t = 3.51 s and the disc has a radius of r = 6.00 cm, what are the x-y coordinates of the chip after this time, assuming the center of the disc is located at (0.00,0.00). X = y = cm cm

6. A uniform disk turns at 3.3 rev/s around a frictionless central axis. A nonrotating rod is dropped onto the disk. The rod has the same mass as the disk and length equal to the diameter of the disk. The two objects then turn together at the same rate with the centers lined up vertically. What is the new angular velocity (in rad/s) and new angular frequency (in rev/s)?

A student is whirling a ball on a string in a circle with an angular speed of 20 rad/s. Air drag decelerates the ball at a rate of -3 rad/s2. What is the angular speed of the ball after it has spun through an angle of 30 radians? Remember to include units with your answer. A disk is initially at rest. If the disk speeds up uniformly to a speed of 45 rad/s in a time of 15 seconds, what angle does it turn through? Remember to include units with your answer.
