Max and maya are riding on a merry-go-round that rotates at a constant speed. if the merry-go-round makes 3.5 revolutions in 9.2 seconds, what is its angular speed?

Angular speed is given by 

w = number of revolutions/ total time

w = 3.5 revs / 9.2s = 0.38 revs/s

We can convert this result to radians per second, knowing that 1 rev = 2pi radians

w = 0.38 (2*pi) rads/s = 2.388 rads/ second

The rearrangement of particles in a physical change. hope this
