A student is about to sled down a hill. He stands on a hill which is 30 meters tall and he weighs 40kg what is his GPE

11760J

Explanation:

Given parameters:

Height of hill  = 30m

Weight  = 40kg

Unknown:

Gravitational potential energy  = ?

Solution:

To find the gravitational potential energy, it is the energy due to the position of a body;

     G.PE  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

 Now insert the parameters and solve;

      G.PE = 40 x 9.8 x 30  = 11760J
