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 Number Number 13.3 Start i Number 0 0 A dentist causes the bit 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? Units Units 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/s. Determine the initial angular speed of the fan. m Units End Suppose you are riding a stationary exercise bicycle, and the electronic meter indicates that the wheel is rotating at 13.9 rad/s. The wheel has a radius of 0.480 m. If you ride the bike for 49.1 min, how far would you have gone if the bike could move? Units
