Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 2.37 x '10\"3 rad/s, while the other has an angular speed of 5.48 x 10'3 rad/s. How long will it be before they meet? Number a 13.3 Units m v A dentist causes the bit of a high-speed drill to accelerate from an angular speed of 1.46 x 104 rad/s to an angular speed of 4.31 x 104 rad/s. In the process, the bit turns through 2.80 x 104 rad. Assuming a constant angular acceleration, how long would it take the bit to reach its maximum speed of 8.79 x 104 rad/s. starting from rest? Number I J Units V] ' An electric fan is running on HIGH. After the LOW button is pressed, the angular speed of the fan decreases to 87.3 rad/s in 1.66 s. The magnitude of the angular deceleration is 47.9 rad/52. Determine the initial angular speed of the fan.
