The highest point on the American eagle roller coaster is 39 meters above the ground. Find the potential energy of a 625 kg roller coaster car that is at its highest point on the track. Use g=10m/s

243.75kJ

Explanation:

Step one:

Given parameters

Height= 39meters

mass= 625g

g= 10m/s

Required

The potential energy PE

Step two:

the expression for the potential energy is given as

PE=mgh

PE=625*10*39

PE=243750 J

PE=243.75kJ

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
