Aboat crosses a river of width 161 m in which the current has a uniform speed of 1.09 m/s. the pilot maintains a bearing (i. e., the direction in which the boat points) perpendicular to the river and a throttle setting to give a constant speed of 2.77 m/s relative to the water. what is the magnitude of the speed of the boat relative to a stationary shore observer? answer in units of m/s.

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?
