Answer:the mass of the child is not given and the question is not complete

but heres the solution.

Using the law of conservation of energy

Initial gravitational energy = work done by friction + work done gained by kinetic energy

mgh = w + 0.5m

w =29kg ×9.8m. ×13m – 0.5×29kg×1.70m.

w =3669.95 J

Below is an attachment containing the solution.
