1. The problem statement, all variables and given/known data The graph (see image in part 3) illustrates how the amplitude of a car's vertical oscilltions vary withthe frequency of an oscillating surface. I was asked to state the amplitude of the oscillation of the surface. I was told It stayed constant. 2. Relevant equations Nil 3. The attempt at a solution I narrowed it down to x and y. However I cannot justify one over the other.
