The wheel of a toy car rotates about a fixed axes. It slows down from 400 rps to 200 rps in 2 s. Then, its angular retardation in `"rad s"^(-2)` is (rps = revolutions per second)

A flywheel rotates about a fixed axis and slows down from 300 rpm to 100 rpm in 2 minutes (i) What is the angular acceleration in "rad min"^(-2) ? (ii) How many revolutions does the wheel complete during this time ?
