1)A dentist's drill starts from rest. After 4.00 s of constant angular acceleration it turns at a rate of 2.00 ✕ 104 rev/min. a)Find the drills angular acceleration ____rad/s^2 b) Determine the angle (in radians) through which the drill rotates during this period____rad 2)The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 5.0 rev/s in 10.0 s. At this point, the person doing the laundry opens the lid, and a...

Att -0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 25.0 rad/s until a circuit breaker trips at time t = 1.70 s. From then on, it turns through an angle 438 rad as it coasts to a stop at constant angular acceleration Part A Through what total angle did the wheel turn between t = 0 and the time it stopped? Express your answer in...
A wheel rotating about a fixed axis with a constant angular acceleration of 3.0 rad/s2 turns through 3.8 revolutions during a 3.0-s time interval. What is the angular velocity at the end of this time interval? 14 rad/s 9.0 rad/s 10.4 rad/s 12.5 rad/s 22.1 rad/s
A machinist turns on the power to a grinding wheel, which is at rest at t = 0.0 s. The wheel accelerates uniformly for 8.0 s and reaches the operating angular velocity of 80 rad/s. The wheel is then run at that angular velocity for 30 seconds and then the power is shut off. The wheel decelerates uniformly at 5.0 rad/s2 until the wheel stops. Through what total angle has the wheel turned? (a) 2400 radians (b) 3360 radians (c)...
