nail-firing device

Consider the nail-firing device of Example 4.15. When the device works, the nail is fired with velocity, V, with density

               

The device misfires 2% of the time it is used, resulting in a velocity of 0. Find the expected kinetic energy associated with a nail of mass m. Recall that the kinetic energy, k, of a mass m moving at velocity v is k =(mv2)/2.

Example 4.15

The kinetic energy k associated with a mass m moving at velocity ν is given by the expression

           

Consider a device that fires a serrated nail into concrete at a mean velocity of 2000 feet per second, where the random velocity V possesses a density function given by

Find the expected kinetic energy associated with a nail of mass m.
