32. In a crash test similar to the one described in
problem 31, another car, with the same mass
and velocity as the first car, experiences an
impulse identical to the value
in problem 31. However, the second car was
designed to crumple more slowly than the
first. As a result, the duration of the interac-
tion was 57.1 ms. Determine the average
force exerted on the second car.
