An object with a mass of 10.00kg is launched from the ground with an initial upward velocity of 95.00m/s near the surface of Earth. Consider a linear model of the air resistance, kv, with v being the variable velocity and k = 0.0365 kg/s?. Take the ground as the origin and upwards as positive direction. Which of the following best describes the DE relating to the problem? Let t be the time, g be the acceleration due to gravity. a. -10.00- 3.285 = 10.00 dv/dt b. -10.00g +0.0365v = 10.00 dv/dt c. -10.00g - 0.0365v = 10.00 dv/dt d. -10.00g – 3.285 = -10.00dv/dt Which of the following is closest to the general solution of the linear DE model, velocity as a function of time? Let C be a real constant, exp()=e0 a. v(t) = 1.346t + C b. v(t) = -2688+Cexp(t/274.0) c. v(t) = -2688+Cexp(-1/10.00) d. v(t) = -2688+Cexp(-1/274.0) %3D Which of the following is closest to the exact solution? a. t) = -2688+2783exp(-t/274.0) b. vt) = -2688+2783exp(-t/10.00) c. t) = -2688+2783exp(t/274.0) d. t) = 1.346t + 95.00 %3D
