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, what is the total energy?

Respuesta :

Total Mechanical Energy = Kinetic Energy + Potential Energy 
Here, K.E. = 500 J
P.E. = 1500 J

Substitute their values, 
E = 1500 + 500
E = 2000 J

In short, Your Answer would be 2000 Joules

Hope this helps!
