An airplane starts its takeoff by moving at 1.7 m/s. the plane must then accelerate at 3.0 m/s2 for the next 30s to reach its final takeoff speed. to the nearest tenth of a kilometer, how far does the plane travel while accelerating to its takeoff speed?

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?
