An accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of
radioactive material present is 46 su (safe units), and 7 months later it is still 40 su.
(a) Write a formula giving the amount A(t) of radioactive material (in su) remaining after t months.
(b) What amount of radioactive material will remain after 11 months?
(c) How long will it be until A = 1 su, so it is safe for people to return to the area?
4. Measured data for pressure versus volume during the expansion of gases within the cylinder of an
internal combustion engine are given in the table below. Using data from the table, complete the
following:
a) Determine a value of n such that the data are fit by an equation of the form pV = const [1.2]
b) Evaluate analytically (using an integral) the work done by the gases based on your result from
part (a) [0.64 kJ]
c) Using graphical or numerical integration on the data (i.e. midpoint trapezoidal rule), evaluate the
work done by the gases [0.65 kJ]
d)
Compare the different methods for estimating the work used in parts (b) and (c). Why are they
estimates?

The power output generated by a windmill depends upon the blade’s diameter (D) and velocity of the wind (V). A good estimate of the power output is given by the following formula: P = (0.01328)D2V3 where P= Power Output (Watts) D = Diameter of the windmill blade in meters V = Velocity of the wind in m/s. Use the Secant method to determine what should be the diameter of the windmill blade if one wishes to generate 800 watts of electric power when the wind speed is 16mph.
