A harmonic oscillator will have a maximum response when an outside force pushes it at the same frequency at the natural frequency of the oscillator A student drives his old car along a road in which contraction lines are etched in the concrete every 47 meters. The driven finds that his car shakes violently when he drives at 28 m/s. Based on this information, what is the natural frequency of the car's vibrations

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
