What are airplane mach numbers?
Mach refers to the speed of sound. A plane that travels at Mach 2 means that it travels twice the speed of sound in air. The actual speed will vary a bit depending on the altitude.Mach number is a measure of relative speed. It is the speed of something relative to a medium, usually air, and divided by the speed of sound in that medium: : : is the Mach number : is the velocity of the object relative to the medium used and : is the velocity of sound in the medium Mach number is the number of times the speed of sound an object or a duct, or the fluid medium itself, move relative to each other. It is named afteran Austrian physicist Ernst Mach.
A fisherman travels downstream at full speed to?
The maximum speed that a vessel will achieve relative to ground is its own maximum speed through water plus the speed of the the moving water downstream.
8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.
How fast in in Mach would you have to go to make it 442 miles in one minute?
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
