Prоblem 4 (25 pоints) Cоnsider the following initiаl vаlue problem аssociated with the response of a nonlinear spring written in non-dimensional state-space form: du / dt = v dv / dt = -ω2 ( 1 + ( u / ubar )2 ) with ω = 1 and ubar = 2 The initial conditions are specified as u(0) = 1 and v(0) = -1 Perform the first two steps of a second order Runge-Kutta method with a step size of Δt = 0.10 to determine approximate solutions at time t = 0.20 Note: This step size is only for illustrative purposes. In practice, a much smaller Δt would be selected.
