Program Explanation Given information: The half-life of radioactive cobalt is 5.27 years. Calculation: The differential equation that relates the number of atoms of radioactive isotope N ( t ) to the time t passed can be written as, d N d t = − k N ....... (1) Separate the variables of the above differential equation as, d N N = − k d t Now integrate the equation on both the sides as, ∫ d N N = ∫ − k d t ln N = − k t + C N = e − k t + C N = e C e − k t Here, C is the constant of integration. Suppose the constant e C is equal to another constant N 0 . Hence, the above equation can be rewritten as, N ( t ) = N 0 e − k t Therefore, the general equation of the differential equation d N d t = − k N can be labeled as, N ( t ) = N 0 e − k t

Suppose we have an 80-lb lead-acid battery. 10% of the weight of the battery is active material on the plates, i.e., we have a total of 8 lb of active Pb and PbO, on the plates that can be used to make electric power. Use the Gibbs free energy method to estimate the total stored energy in the battery. Assume that the open circuit voltage for a lead-acid cell is 2.1 V. [The answer should be a little less than 1 kilowatt-hour of energy.]

2. The flight of a model rocket can be modeled as follows. During the first 0.15 s the rocket is propelled upward by the rocket engine with a force of 16 N. The rocket then flies up while slowing down under the force of gravity. After it reaches the apex, the rocket starts to fall back down. When its downward velocity reaches 20 m/s, a parachute opens (assumed to open instantly), and the rocket continues to drop at a constant speed of 20 m/s until it hits the ground. Write a program that calculates and plots the speed and altitude of the rocket as a function of time during the flight.
