a marble rolls down the ramp and attains velocity of 1m/s if that falls from a height of 3m how far from the base of the ramp would you expect the marble to land

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?
