Answer:

At the top of the hill.

Explanation:

As the roller coaster goes up the hill, kinetic energy (K.E) decreases, gravitational potential energy (G.P.E) increases .

As it reach the top of the hill, K.E becomes zero and G.P.E reaches maximum .

As it goes down the hill, K.E starts to increase and G.P.E decrease .

At the bottom of the hill, K.E reaches maximum and G.P.E becomes zero .

(Correct me it I am wrong)

At the top of the hill.

The following information should be considered:

  • In the case when the roller coaster goes up the hill, kinetic energy (K.E) decreases, gravitational potential energy (G.P.E) increases .
  • When it reach the top of the hill, K.E becomes zero and G.P.E reaches maximum .
  • When it goes down the hill, K.E starts to increase and G.P.E decrease .
  • When it is the bottom of the hill, K.E reaches maximum and G.P.E becomes zero.
