A disk, initially rotating at 123 rad/s, is slowed down with a constant angular acceleration of magnitude 3.96 rad/s2. (a) How much time does the disk take to stop? (b) Through what angle (rad) does the disk rotate during that time?
A disk, initially rotating at 118 rad/s, is slowed down with a constant angular acceleration of magnitude 3.94 rad/s2. A) How much time does the disk take to stop? B) Through what angle does the disk rotate during that time?
A disk rotates with constant angular acceleration. The initial angular speed of the disk is 2.1π rad/s. After the disk rotates through 13.6π radians, the angular speed is 6.2π rad/s. (a) What is the magnitude of the angular acceleration? (b) How much time did it take for the disk to rotate through 13.6π radians? (c) What is the tangential acceleration of a point located at a distance of 9.9 cm from the center of the disk?
A disk is initially rotating (about its center) at 48 rad/s counter-clockwise. After a constant angular acceleration is applied to it for 2.2 seconds, it is rotating at 9 rad/s counter-clockwise. How many revolutions does the disk make in that time
At time t=0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 35.0 rad/s^2 until a circuit breaker trips at time t= 2.50 s. From then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration. a.) Through what total angle did the wheel turn between t= 0 and the time it stopped? answer in rad b.) At what time does the...
