Asteel beam is rotated in a horizontal plane to provide the
centripetal acceleration for training pilots. if a 80 kg pilot
sits 6.7 m from the center of rotation, at what speed (in
m/s) must he rotate to experience a horizontal
centripetal force of 4950 n?

In 1980, alfa romeo introduced the first system to smooth a rough idle caused by ignition and camshaft timing changes.

What would be the strength of earth's gravitational field at a point where an 80.0 kg astronaut would experience a 80% reduction in weight

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?
