Question

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

Answer 1

Answer:

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
