A disc of moment of inertia 29.1 kg m2 is made to rotate about an axis through its centre by a torque of T . The disc starts from rest and, after {t} s, has kinetic energy {k} J.(adsbygoogle = window.adsbygoogle || []).push({});

The torque is removed when the disc is rotating at 8.0 rad s-1 . An opposing torque of 13.2 N m is applied to slow the disc down.

Calculate the number of revolutions the disc makes after the second torque is applied, before it comes to rest.

how do i approch this problem (if numbers were involved) i would have to calculate the angular acceleration and then tention. after t seconds

any help would be apprecated thanks in advance
