A disk is originally spinning about its center at 6 rad/s counter-clockwise. A constant angular acceleration (about its center) is applied to it and it stops spinning after 6 seconds. How many revolutions are made before it is stopped?
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
A disk is originally spinning about its center at 4.8 rad/s clockwise. It makes 3.6 revolutions before it is stopped. If under a constant angular acceleration, how long does it take to stop in seconds?
Question 7 8 pts A disk is rotating at 21 rad/s counter-clockwise about its center and a constant angular acceleration of 4 rad/s? is applied to it clockwise. After 0.69 seconds, what is its rotational kinetic energy about its center if c 1/2, the mass of the disk is 4 kg, and its radius is 0.74 meters? Answer in Joules.
2. The disk starts from rest and is given an angular acceleration a = (21) rad/s, where 1 is in seconds. Determine the angular velocity of the disk and its angular displacement when 1 = 4 s.
A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it is rotating at 4.20 rev/s; 75.0 revolutions later, its angular speed is 23.0 rev/s. Calculate (a) the angular acceleration (rev/s2), (b) the time required to complete the 75.0 revolutions, (c) the time required to reach the 4.20 rev/s angular speed, and (d) the number of revolutions from rest until the time the disk reaches the 4.20 rev/s angular speed. _...
A hollow disk is rotating about its center at 5 rad/s. Friction is acting on the disk at the axis of rotation producing an angular acceleration of 1 rad/s. How many revolutions will the disk rotate before coming to a stop?
A disk with a mass of 15 kg is spinning about its center with a constant angular acceleration applied to it. Its c value is 1/2 about its center and it is initally spinning at 5 rad/s clockwise. If the disk stops spinning in a time of 1.5 s, how many revolutions does the disk make until it stops? 1.79 rev. 3.75 rev. 11.25 rex 0.60 rev. MacBook Pro $ % 5 & 7 8 E R T Y F...
A thin disk begins to rotate from rest with a constant angular acceleration. The disk takes 1.2 seconds to make its second complete revolution. Find: 1) the time (in sec) it took the disk to make its first revolution; 2) the angular acceleration (in rad/sec2) of the disk.
Starting from rest, disk A begins rotating with a counterclockwise angular acceleration of 3t rad/s2 (where t is time in seconds). For disk D, calculate the angular acceleration, angular velocity, and the number of revolutions after5 seconds. RA 200 mm Re 100 mm Rc 175 mm Ro 150 mm A/ 0 RB
