A uniform rod of mass `m` and length `l` can rotate in a vertical plane about a smooth horizontal axis point `H`. a. Find angular acceleration `alpha` of the rod. just after it is released from initial horizontal position from rest'? b. Calculate the acceleration (tangential and radial) , point A at this moment.

Explanation

`a_(tauA) = al = (3g)/(2l) * l = (3g)/(2)`
`a_(CA) = omega^(2) r = 0 . l = 0 `
(` :. omega = 0 ` just after release)
