    Solving Newton's 2nd Law Problems: Blocks & Crate

    Hi, I'm having trouble with these problems dealing with Newton's 2nd Law 1] Two blocks are in contact on a frictionless table. A horizontal force is applied to the larger block, as shown in Fig. 5-50. (a) If m1 = 2.0 kg, m2 = 1.4 kg, and F = 2.7 N, find the magnitude of the force between the...

    How can I mathematically model the flow of new currency into circulation?

    Homework Statement A small country has $10 billion in paper currency in circulation, and each day $50 million comes into the country's banks. The government decides to introduce currency by having the backs replace old bills with new ones whenever old currency comes into the banks. Let L=L(t)...

    Differential EQ Homework: Model Population Growth with dP/dt = kP(1-P/C)

    I did the phase line test. P>4200, the population is decreasing. So if the population gets over the capacity, it will die off because that area/town/city's limit is 4200 capacity. So the equilibrium is 4200? sorry I kind of don't understand equilibrium. Does that mean its where you set the Diff...

    Differential EQ Homework: Model Population Growth with dP/dt = kP(1-P/C)

    Homework Statement A population increases exponentially in its stages, but cannot continue forever. C = carrying capacity. Model rate of population change by dP/dt = kP(1-P/C) for P=population size Homework Equations 1] a population is model dP/dt = 1.2P(1-P/4200) 2] For what value...
