Question

A baby carriage that is carrying twins is sitting at the top of a knoll that is 21 m high. The carriage with the babies is 48kg. What is the Potential Energy of the twins and the carriage? i have to do it with Potential Energy = Weight x HeightWeight = Potential Energy / HeightHeight = Potential Energy / WeightWeight = Mass x 10Mass = Weight / 10

Answer 1

In order to calculate the potential energy of an object, we can use the formula below:

$PE=m\cdot g\cdot h$

Where m is the mass (in kg), g is the gravity acceleration (in m/s²) and h is the height (in meters).

Since mass times gravity is equal to the weight force, we can also write the equation as follows:

$PE=W\cdot h$

Where W is the weight force.

Therefore the answer is:

Potential Energy = Weight x Height
