If the horizontal circular path the riders follow has a 7.00 m radius, at how many revolutions per minute will the riders be subjected to a centripetal acceleration whose magnitude is 2.25 times that due to gravity?

centripetal acceleratrion can be expressed as:
Where
Substituting in values:
solving for
Angular velocity is the rate of change of angle
Where T = time period (time for one revolution)
Hence we can solve for T
So it completes one revolution every 3.5s. In one minute it will complete:
