(Tyre rotation during a journey)
(a) A car tyre makes 7.5×103 complete revolutions during a short trip.
(b) (a) Calculate the total angle turned by the tyre in degrees.
(c) (b) Convert the answer obtained in part (a) to radians, giving it (i) in terms of π and (ii) correct to three significant figures.
(d) (c) Express the same angular displacement in revolutions, degrees, and radians per second if the trip lasted 12 minutes.
