Answer:3
Step-by-step explanation:
Answer:
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.
