Abody of mass 2 kilograms moves on a circle of radius 3 meters, making one revolution every 5 seconds. find the magnitude of the centripetal force acting on the body. (be sure to correctly state the units of the force.

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?
