Question

Calculating Potential Energy
A roller coaster train with a mass of 500 kg stops at the top of a hill. If the hill is 110 m high, what is the potential
energy of the train?
O 4,900 J
O 5,612J
0 55.000 J
539,000

Answer 1

Answer:

D. 539,000 J

Explanation:

The formula for potential energy(P.E) =mgh where m is mass of object, g is gravity acceleration 9.8 m/s² and h is height in meters.

From the question ;

m=500 kg

g= 9.8 m/s²

h= 110 m

P.E = mgh

     = 500*9.8*110

     =539,000 J

 Answer option D

The other options are incorrect because the calculated values for the potential energy of the train are not equal to 539,000 J.
