2) A certain particle moves by a special type of fluid which has a resistance R that depends on the speed v with which the particle moves. To calcthe displacement time of the particle when its velocity changes, the following model is used where m is the mass of the particle: \int_{v_i}^{v_f} \frac{m}{R(v)} dv If resistance is known to be a velocity-dependent force and R(v) = -v\sqrt{v} is calculated and that the mass of the particle is 8 kg, determine how long it takes for this particle to reduce its velocity from 10 m/s at 6 m/s using the methods seen: a) Sort the data of the problem and propose the integral to be solved. b) Calculate an approximation using the compound trapezoid or composite midpoint method with n = 8 (only one of the two) c) Use Simpson's method compound with n = 8. (To facilitate the calculations you can use only five decimal places of approximation)
