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,

W = P.E = mgh joules

Substituting the values,

W = 12 x 9.8 x 21

= 2469.6 J

Hence, the carriage has the energy, W = 2469.6 J
