You’re riding in a friend’s 1400-kg car with bad shock absorbers, bouncing down the highway at 20 m/s and executing vertical SHM with amplitude 18 cm and frequency 0.67 Hz. Concerned about fuel efficiency, your friend wonders what percentage of the car’s kinetic energy is tied up in this oscillation. Make an estimate, neglecting the wheels’ rotational energy and the fact that not all of the car’s mass participates in the oscillation
