  (a) The motion of a small ball bearing dropped into viscous oil can be modelled by Equation 1 , where \( m \) is the mass of the ball, \( r \) is a constant related to the viscosity of the oil, \( g \) is the magnitude of the acceleration due to gravity, and \( x \) is the vertical distance from the point of release. i. Determine the general solution for the vertical distance from the point of release. ii. Show that the velocity of the ball approaches the limiting value \( \mathrm{mg} / \mathrm{r} \) as time \( (t) \) becomes very large. \[ m \frac{d^{2} x}{d t^{2}}+r \frac{d x}{d t}-m g=0 \]

Air at 80 degrees Fahrenheit and 14.7 psia with a mass flow rate of 0.6 lbm/sec enters a compressor and leaves at 70 psia and 430 degrees Fahrenheit through an exit area of 0.007 ft^2.  The measured heat interaction rate with the 80 degree Fahrenheit factory room is 3 Btu/sec.  Use constant Cp = 0.24 Btu/lbm oF a) Calculate the compressor work rate.   b) Compute the entropy generation rate for the overall process.
