Answer:

980J

Explanation:

Given parameters:

Mass of the child  = 25kg

Height of the slide  = 4m

Unknown:

Gravitational potential energy  = ?

Solution:

To solve this problem, we have to use the expression below:

       Gravitational potential energy is the energy due to the position of a body.

It is mathematically expressed as;

  G.PE  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

 G.PE  = 25 x 9.8 x 4= 980J
