The expansion joints of a concrete highway, which are located at \(15-\mathrm{m}\) intervals, cause a series of impulses to affect cars running at a constant speed. Determine the speeds at which bounce motion and pitch motion are most likely to arise for the car of Example 5.7.

Data From Example 5.7:-
