A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 272-mile trip in a typical midsize car produces about 3.25 x 10° J of energy. How fast would a 18.3-kg flywheel with a radius of 0.303 m have to rotate to store this much energy? Give your answer in rev/min. Number i Units

2 W S X 24919 3 E D C 3. A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.45 x 10¹ rad/s to an angular speed of 3.75 x 104 rad/s. In the process, the bit turns through 2.26 x 10¹ rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 7.10 x 10 rad/s, starting from rest? $ R F V % 5 19 T G tv B MacBook Air 6: Y H & 7 N 44 U ★ 8 J P M ( 9 K MOSISO V H 2 command 4 option y m 04 M
