A mass weighing 8 pounds stretches a spring 4 feet. The medium through the mass moves offers a damping force numerically equal to sqrt(2) times the instantaneous velocity. Find the equation of motion if mass is released from equilibrium position with a downward velocity of 5 ft/s. Find the time at which the mass attains its extreme displacement from the equilibrium position. What is the position of the mass at this instant? The acceleration of gravity is g = 32...

The number of imperfections in an object has a Poisson distribution with a mean λ = 8.5. If the number of imperfections is 4 or less, the object is called "top quality." If the number of imperfections is between 5 and 8 inclusive, the object is called "good quality." If the number of imperfections is between 9 and 12 inclusive, the object is called "normal quality." If the number of imperfections is 13 or more, the object is called "bad...
