The roller coaster does not have kinetic energy at the top of the hill
It probably is because of the engine the pulls the coaster to the top
74mph is the top speed
Intamin
It depends on the roller coaster's height,speed,and location. :p
420 Ft. Top Thrill Dragster. This coaster is currently the second tallest coaster in the world
15 mph
They don't.
If on top of the roller coster is moving it is kinectic if not potential
When the roller coaster is at its highest position and is not moving then its potential energy is highest
2,800 feet
The top speed is when the ride gets up to the top speed allowed.
