Ababy's car seat sits on top of a bench 2 m tall. the baby and the car seat have a weight of 12 n. find the energy of the baby and its car seat.

24 J

Explanation:

Given:

Baby is sitting on a bench at height = 2 m

Weight of baby and car seat = 12 N

To find energy of baby and its car seat.

Solution:

Since the baby and the car seat are stationary i.e. in rest, so the energy possessed by them would be in the form of potential energy.

The potential energy is give as:

where represents mass of the body, represent the acceleration due to gravity and represent the height.

The weight of body is product of mass and acceleration due to gravity and is given by:

Substituting the product of with and writing the energy equation as:

Plugging in the known values, we have:

∴  [ Since energy is given in Joules] (Answer)

its a 5.5 n
