A \(75.0\,\text{kg}\) log floats downstream with a speed of \(1.80\,\text{m/s}\). Eight frogs hop onto the log in a series of perfectly inelastic collisions. If each frog has a mass of \(0.30\,\text{kg}\) and an upstream speed of \(1.3\,\text{m/s}\), what is the change in kinetic energy for this system?
