  Usually, this refers to an Anterior Cruciate Ligament tear, where the knee is in a fixed position and a twisting force is applied to it. This manifests itself as knee we â¦ akness when weight is put on it, with the sensation of the knee slipping forward. Damage of the meniscal cartilage around it is also common.
A wheel starts from rest and has an angular acceleration that is given by Î±(t) = (6.0 rad/s4)t2. The time it takes to make 10 rev is: B. 3.3 seconds. A wheel starts from rest and has an angular acceleration that is given by Î±(t) = (6.0 rad/s4)t2. After it has turned through 10 rev its angular velocity is: B. 75 radians per second. A wheel is spinning at 27 rad/s but is slowing with an angular acceleration that has a magnitude given by (3.0 rad/s^4)t^2.
Angular Acceleration. When an object is in motion then its velocity is changed continuously then it is called in acceleration state. We know that acceleration is the change in velocity of moving object with respect to time. When an object is moved on circular path then its velocity is the angular velocity.The angular velocity is in the perpendicular direction of the rotational plane and it is related to the change in the angular speed and measure with unit as radians per second or revolutions per second.s mentioned earlier, the definition of average angular velocity is the change in angle $\theta$ with respect to time t. where, $\theta$ is the angle rotated in the time t. Now we will bring in the linear velocity v and the radius of the circle r, in a circular motion.
