**10. A 100-kg man gets inside an old clunker car that he is thinking of buying, and he deter- mines that the car drops 1.0 cm closer to the ground when he is in it. a) What is the effective spring constant of the springs in the car? b) As he test drives the car, he hits a bump and discovers that the shock absorbers are shot, so there is no damping of the vibrations. The car with him inside it vibrates with a period of 0.75 s. What is the mass of the car alone?

A 75 kg student jumps off a bridge with a 12-m-long bungee cord tied to his feet. The massless bungee cord has a spring constant of 430 N/m. a) How far below the bridge is the student’s lowest point? b) How far below the bridge is the student's resting position after the oscillations have fully stopped?
Vision is blurred if the head is vibrated at 29 Hz because the vibrations are resonant with the natural frequency of the eyeball held by the musculature in its socket. If the mass of the eyeball is 7.5 g, a typical value, what is the effective spring constant of the musculature attached to the eyeball?
