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
