250 kg roller coaster car has 20000 J of potential energy at the top of the hill what is the velocity of the car at the bottom of the hill?

Kinectic energy is the same as potential energy - so 20000 is the sames as half x m x vsquared - therefore 20000 is half 250 which is 125 - 20000 divided by 125 is velocity squared so then square root your answer and there it is

Does a roller coaster have more potential energy at the top of the hill or at the bottom?
A roller coaster has more potential energy at the bottom. There are 2 types of energy, potential and kinetic. energy closer to a surface or floor is potential energy and objects in the middle of it all has kinetic energy.
How does something turn from kinetic energy to potential energy?
kinetic energy is energy in motion. potential is like a roller coaster you start at the bottom and go up to highest point of the coaster and yougain potential energy as you move to the highest point of the coaster and when you go down the peak point the potential energy the coaster was gaining is transferred to kinetic energy.
Where will you locate on a pendulum or roller coaster the greatest potential and greatest kinetic energy?
On a pendulum, the greatest potential energy is at the highest point of the swing on either side, and the greatest kinetic energy is at the bottom of the swing. On a roller coaster, the greatest potential energy is at the top of a hill, and the greatest kinetic energy is at the bottom of the hill.
What part of the roller coaster has kinetic energy?
Mechanical Energy encompasses both Kinetic and Potential energies. A roller coaster is a perfect example of both. At the very top of a hill, the roller coaster has a lot of potential energy due to position above the earth. As it goes down a hill, this potential energy decreases as it gets closer to the earth, and it's kinetic energy increases as it gets faster. KE = energy of motion PE = potential energy due to position above the earth ME = KE+PE
On a Roller Coaster where is the potential energy?
When the roller coaster is at its highest position and is not moving then its potential energy is highest
Where is potential energy on a roller coaster?
When the roller coaster is at its highest position and is not moving then its potential energy is highest
When does a roller coaster increase kinetic energy?
The roller coaster increases kinetic energy when its velocity is increasing.
How do gravity and potential energy work together to give you a great ride on a roller coaster?
the gravitational potential energy of a roller coaster is equal to two things. Not only is it equal to the gravitational potential energy, it is also equal to the kinetic energy at the lowest point of the coaster. the gravitational potential energy can be calculated as: m*g*h where m is mass (kilograms), g is gravity (9.8 m/s^2), and h is height (metres).d the kinetic energy at the bottom of the coaster can be calculated as (m*v^2)/2 where m is mass (kilograms), v is velocity (metres/second).
Is energy potential?
yes it is
Where is the greatest amount of potential and kinetic energy in a roller coaster?
If it is a rollercoaster that has a first drop hill, the roller coaster has the greatest kinetic energy at the bottom of that drop. If it is magnetically launched, the kinetic energy is probably greatest immediately after the launch. However, there are cases where these statements may not be true. (i.e. a drop right after a magnetic launch)The energy is the greatest at the bottom of a drop, before some is translated back into potential energy as the car climbs the next rise.
Does a roller coaster car have potential energy?
It depends on where the zero potential energy level is taken. If it is the ground, and the car is at the bottom of a ramp ON A TABLE, then it will have Ep. If the bottom of the ramp was taken as the zero Ep level, then it will have zero Ep.
Where does a roller coaster have the least kinetic energy?
At the tallest point on the track. Potential energy is given by U(Which is potential energy) = mass times height time gravitational constant. You can't change the gravitational constant, or the mass of the roller coaster car. So you have to change the height. PE=mgh so more the height and the mass the more PE
