Question

What is the energy of a baby who weighs 20 N sitting on a 1.5 m high chair

Answer 1

Answer:30 j

Step-by-step explanation:

Is right I just checked it in class

Answer 2

The energy of the baby is gravitational potential energy, and it is equal to the weight of the baby times its height from the ground:

`U=(mg) h`
where
mg=20 N is the weight (the mass times the gravitational acceleration)
h=1.5 m is the height from the ground
If we plug the numbers into the equation, we find

`U=(mg)h=(20 N)(1.5 m)=30 J`
