For a school project, Robert records the motion of a snail and plots a position-time graph of the data. From the graph, the distance the snail travels in the first 20 seconds is
centimeters. After that, the snail remains in the same place for
seconds.

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?
