Calculate m for an airliner cruising

Assignment Help Physics
Reference no: EM132438876

Mach number M is a dimensionless quantity equal to the ratio of the speed of the aircraft to the speed of sound in the air, approximately 342 m/s. At M = 1 the aircraft is said to "break the sound barrier".

(a) Calculate M for an airliner cruising at 800 km/hr.

(b) How fast does an aircraft need to travel to reach M = 2? Express the speed in km/hr.
