  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 deals with angles in a circle -- in common terms RPM, or revolutions per minute. Velocity, as we commonly know it, is distance divided by time. To make things simple, we can calculate Angular Velocity first and use it to quickly find Linear Velocity. Remember in Geometry that we calculated the arc length. Given a radius of 4 and a central angle of 50... S = (50/360)â¢ 4â¢4Ï = 20Ï/9.
