If a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, it’s total energy is

E = 2000 J

Explanation:

Given data:

Kinetic energy = 500 J

Potential energy = 1500 j

Total energy = ?

Solution:

Formula:

E = K.E + P.E

Now we will  put the values.

E = 500 j + 1500 j

E = 2000 J

the answer is   c.) 1575 j.

explanation:

the dependant variable is spilled water

the independent is the heat
