Edmunds.com bases the luxury type on the model's nameplate: Audi, BMW, Cadillac, Lexus, Mercedes-Benz and the like. However, some listed vehicles bear the nameplates of brands that are not typically considered luxury marques. These vehicles typically achieve luxury status because of their price.
A bowling ball encounters a 0.760 m vertical rise on the way back to the ball rack. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 4.70 m/s at the bottom of the rise. Find the translational speed at the top. Add your answer.
M is the Mach number, u is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and. c is the speed of sound in the medium. By definition, Mach 1 is equal to the speed of sound. Mach 0.65 is 65% of the speed of sound (subsonic), and Mach 1.35 is 35% faster than the speed of sound (supersonic). The local speed of sound, and thereby the Mach number, depends on the condition of the surrounding medium, in particular the temperature.
