A discus thrower starts from rest and begins to rotate with a constant angular acceleration of 2.5 rad/s2 . A. How many revolutions does it take for the discus thrower's angular speed to reach 5.6 rad/s ? B. How much time does this take?
An object that is initially at rest begins to rotate under a constant angular acceleration of 1.56 rad/s2. How long does it take the object to undergo an angular displacement of 234 rad?
Starting from rest, a discus thrower accelerates a discus to a final angular velocity of 13.1 rad/s in a time of 0.286 seconds before releasing it. If her arm extends 0.625 m from her body, find the tangential acceleration of the discus.
To throw the discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.7 m . Part A If the thrower takes 0.90 s to complete one revolution, starting from rest, what will be the speed of the discus at release? Express your answer in meters per second.
A fan blade starts at rest and begins moving with a constant angular acceleration of 2.00 rad/s2. The blade rotates through an angle of 285 radians in an 11.0 s interval that did not start at t = 0s. How long did it take the blade to reach the beginning of the 11.0-s interval? Answer must be in seconds.

To throw a discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.8 m. If the thrower takes 1.0 s to complete one revolution, starting from rest, what will be the speed of the discus at release?
To throw the discus, the thrower holds it with a fully outstretched arm. Starting from rest, he begins to turn with a constant angular acceleration, releasing the discus after making one complete revolution. The diameter of the circle in which the discus moves is about 1.7 m . If the thrower takes 1.1 s to complete one revolution, starting from rest, what will be the speed of the discus at release?
A helicopter blade starts to rotate from rest with a constant angular acceleration of \alpha=\: α = 0.65 radians/second2. How many revolutions will the blade make before it is rotating at 500 revolutions per minute (RPM)?
A helicopter blade starts to rotate from rest with a constant angular acceleration of \alpha=\: α = 0.76 radians/second2. How many revolutions will the blade make before it is rotating at 500 revolutions per minute (RPM)?
