  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.
Explanations and/or setups would be great :). A wheel with radius of $5$ feet is rotating at $100$ rpm. a) Determine the angular speed of the wheel in radians per minute. b) Determine the linear speed of a point on the circumference of the wheel in feet per minute. So we got this as homework today, and I just don't understand it; how to start or how to do it.
