Atypical value for the coefficent of quadratic air resistance on a cyclist is around c=0.20 n/m(m/s)2. assuming thath the total mass (cyclist plust cycle) is m = 80 kg and that at t = 0 the cyclist has an intial speed v=20m/s (abouit 45 mi/h) and starts to coast to a stop under the influence of air resistance, find the characteristic time τ=m/cvo. how long will it take him to slow to 15 m/s? what about 10 m/s? and 5 m/s? (below about 5 m/s, it is certainly not reasonable to ignore friction, so there is no point pursuing this calculation to lower speeds.)

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

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?
