On a certain game show, contestants spin a wheel when it is their turn. One contestant gives the wheel an initial angular speed of3.10rad/s. It then rotates through one-and-one-quarter revolutions and comes to rest on the BANKRUPT space. Through what angle has the wheel turned when its angular speed is1.55rad/s?
