A baby with a mass of 10.6 kg bounces up and down in his crib. The crib mattress behaves like a light spring with force constant 506 N/m. (a) The baby bounces with at a frequency that allows his to reach a maximum amplitude with minimum effort. What is this frequency (in Hz)? Hz (b) The baby now bounces high enough to lose contact with the mattress once each cycle, like a trampoline. What is the minimum amplitude of oscillation (in cm) required for this to occur? cm

Forced undamped vibrations

In mechanical engineering, vibration is expressed as the term that occurs due to an object's backward and forward movement about a point of equilibrium. Generally, there are three types of vibrations which are,
