A train is moving East with a constant speed of $V_T = 40$ kph. Meanwhile, a man walks in the west direction on top of the train at speed of $V_{M/T} = 10$ kph relative to the train. He accelerates uniformly at a rate of $a_M = 5 m/s^2$. At this same instant, Car C starts to round a curve at A with an initial speed of $(V_C)_A = 60$ kph. After $t = 2.EFG$ s, the car reaches point B of the curve where it has uniformly reduced its speed to $(V_C)_B = 50$ kph. Determine the velocity (in kph) and acceleration (in $m/s^2$) of the man relative to the car at $t = 2.EFG$ s.

Answer the following questions by explaining which program you can use to solve each question, how you prepare the arguments for the program and what is command to use. Q1: Consider the following set of equations. \begin{align*} 10x_1 - x_2 + 2x_3 &= 6 \ -x_1 + 11x_2 - x_3 + 3x_4 &= 25 \ 2x_1 - x_2 + 10x_3 - x_4 &= -11 \ 3x_2 - x_3 + 8x_4 &= 15 \end{align*} Explain which program (Iterative Method) you can use for solving the above system. Use a precision of $10^{-4}$ and start with $x^{(0)} = (0,0,0,0)$ A) Newton Method B) Gauss Elimination C) Gauss-Seidel Method D) Bisection
