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 dа ta:

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
