7 yearIt's another Saturday night and you are stuck babysitting little Maria and Marco Lightbourne. As you watch TV while 3 year old Maria plays with her puzzles and 7 year old Marco plays on his tablet, you find yourself feeling tired and weary from the long week of tests and projects. Suddenly, you are awoken by Marco who calmly asks if he can have a snack. As you quickly regain composure, you are frightened by the scene in front of the TV. Little Maria is lying, sprawled out on the floor and her lips have turned distinctively blue. All of the information you learned in your babysitting course comes flooding back to you and you jump into action. What do you do?

Blue lips in children may be as a result of lack of oxygen or constriction inhibiting proper breathing.

Maria may have swallowed one of the puzzles unconsciously which may have blocked her throat and lungs affecting her breathing.

Maria should be seated upright and her mouth checked to clear and remove any object blocking her throat or lungs or constricting her from getting sufficient and adequate oxygen which may cause her lips turning bluish making her feeling distressed on the floor.

Explanation:

Blue lip may occur when the skin on the lip becomes a bluish tint or color.

This is due to either a lack of sufficient oxygen in the blood or to extremely cold temperatures. When the skin becomes a bluish color, the symptom is generally called cyanosis. Mostly, blue lips are caused by a lack of oxygen in the blood.

we can solve this via the kinematic equation:

where the vertical velocity is zero and so:

since the height of the building is 29.3 meters then:

the ball was in motion for approximately 2.45 seconds
