An airplane flies horizontally at constant speed in a straightÂline direction. its state of motion is unchanging. in other words, it is in equilibrium. two horizontal forces act on the plane. one is the thrust of the propeller that pulls it forward. the other is the force of air resistance (air friction) that acts in the opposite direction. which force is greater?

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 Ëšf and standard atmospheric pressure, what is the value of the mach number?
