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 are 48kg. What is the Potential Energy of the twins and the carriage?

The Potential Energy of the twins and the carriage is 9878.4 J.

Step-by-step explanation:

Given;

height of the knoll above the ground level, h = 21 m

mass of the carriage with the babies, m = 48 kg

The potential Energy of the twins and the carriage is given by;

P.E = mgh

where;

g is the acceleration due to gravity = 9.8 m/s²

Substitute the givens;

P.E = (48)(9.8)(21)

P.E = 9878.4 J

Therefore, the Potential Energy of the twins and the carriage is 9878.4 J.
