  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.
To specify the sense of rotation we use a convention called the right-hand rule. If the fingers of your right hand are curling to indicate which way the wheel is turning, then the thumb of you right hand is pointing in the direction of the axis of rotation. This is the direction of the angular velocity.
