hi there could you please help solve the question 2-4 in typed text, cause hand writing is sometimes hard to read.

the subject is math modeling

here are the typed text for your reference, equations are represented by ...

1.for a ball of radius T and mass density p, moving through a viscous fluid ...witg viscosity u, one model giving its motion is given by ... with V is the velocity and of is the density of the fluid. nondimensionalized this equation.

2.check that ... is a solution the nondimensionalized equation in problem 1c and finds in terms of the orginal parameters.

3.prove that ... is a stationary solution of the predator-prey model with fiction ...

4.three cows are in the road eaten following ...ahead of it. If the first ve has speed given by ... write down th differntical equation of the velocity of the following cows it they respect the GHR model with parameters...
