Respuesta :

Answer:

11760J

Explanation:

Given parameters:

Mass of the student  = 40kg

height  = 30m

Unknown:

Gravitational potential energy  = ?

Solution:

The gravitational potential energy of a body is due to the position of the body.

  GPE  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

  GPE  = 40 x 30 x 9.8  = 11760J
