Question: One of the greatest difficulties with setting up the baby bouncer is determining the right height above the floor so that the child can push off and bounce. Knowledge of physics can be really helpful here.
If the spring constant (k=5.0 x 10^2 N/m) , the baby has a mass (m=11kg) , and the baby's legs reach a distance (d=0.15m) from the bouncer, what should be the height (h)of the "empty" bouncer above the floor?
