An old car with worn-out shock absorbersoscillates with a given frequency when it hits a speed bump. Ifthe driver adds a couple of passengers to the car and hits anotherspeed bump, (a) is the car’s frequency of oscillation greater than,less than, or equal to what it was before? (b) Choose the best explanation from among the following:I. Increasing the mass on a spring increases its period, andhence decreases its frequency.II. The frequency depends on the force constant of the springbut is independent of the mass.III. Adding mass makes the spring oscillate more rapidly, whichincreases the frequency
