The suspension of a modified baby bouncer is modelled by a model spring 9 A with stiffness k1 and a model damper T A with damping coefficient r. The seat is tethered to the ground, and this tether is modelled by a second model springAS with stiffness k2. Model the combination of baby and seat as a particle of mass m at a point A that is a distance r above floor level. The bouncer is suspended from a fixed...

1. Suppose that a car weighing 4000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6500 lbs/foot, so the effective spring constant for the system of 4 shock absorbers is 26000 lbs/foot.1. Assume no damping and determine the period of oscillation of the vertical motion of the car. Hint: g= 32 ft/sec22. After 10 seconds the car body is 1 foot above its equilibrium position and at the high point in its cycle....
