Vibrations Question The following is used to model a wave that impacts a concrete wall created by the US Navy speed boat. Derive the complete piecewise function of F(t) and F(tau) The concrete wall is 2.8 m long with a cross-section area of 0.05 m2. The force at time equal zero is 200 N. It is also known that the mass is modeled as lumped at the end of 1200 kg and Young’s modulus of 3.6 GPa
