Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Step-by-step explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E =
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.
