Question 1
A string fixed at both ends vibrates according to the equation \( \frac{\partial^2 u}{\partial t^2} = 16 \frac{\partial^2 u}{\partial x^2} \). If the initial conditions are \( u(x,0) = 0 \) and \( \frac{\partial u}{\partial t}(x,0) = 10 \sin(\frac{\pi x}{L}) \), find the solution for \( u(x,t) \).
💡 Hint: Apply separation of variables and use Fourier series expansions.
Question 2
Consider a wave traveling in a string modeled by the equation \( \frac{\partial^2 u}{\partial t^2} = 25 \frac{\partial^2 u}{\partial x^2} \). If the free end at x = L has an amplitude of 5 cm, derive the expressions for displacement and motion at x over time.
💡 Hint: Identify the wave parameters and relate them back to the wave equation.
