Challenge Problems

Push your limits with challenges.

Question 1

Consider a mechanical system modeled by dx/dt = -0.5x + 2y, dy/dt = 4x - y. Using initial conditions x(0)=1, y(0)=0, derive the solution for both variables.

💡 Hint: Remember the transformation steps and rearrangement strategy.

Question 2

A control system utilizes two state variables with dynamics described by dy/dt = 3x - 4y and dx/dt = -2y + x. Using Laplace methods, verify if the system converges over time given initial conditions.

💡 Hint: Focus on evaluating the roots of the characteristic polynomial derived from the equations.
