Answer:
The carriage has the energy, W = 2469.6 J
Explanation:
Given data,
The height of the hill, h = 21 m
The carriage with the baby weighs, m = 12 kg
The energy possessed by the body due to its position is the potential energy,
<em>W = P.E = mgh joules</em>
Substituting the values,
W = 12 x 9.8 x 21
= 2469.6 J
Hence, the carriage has the energy, W = 2469.6 J
