A merry-go-round is accelerated from rest by a child at a steady acceleration of 0.2 rad.s-2. 1)How long does it take for the merry go round to reach an angular velocity of 1.4 rad.s-1? 2)How many revolutions does the merry go round (and the child) make in this time? I belive I worked out the first one, where a=w/t. so t=w/a (t=1.4/0.2). Am I correct?. However I can't understand the second part..is there an equation to find the number of revs?
