A 45 kg skater is skating down a hill on roller blades at a a speed of 10 ms what is the kinetic energy of the skater?
KE = 1/2mV2 KE = 1/2(30 kg)( 5m/s)2 = 750 joules of kinetic energy ===================
The conversion of potential energy to kinetic energy demonstrates the what?
mechanical energy
What type of energy does a rollercoaster use?
potential when it starts ,then kinetic when it starts to move ,then lights if the roller coaster has lights ,then heat because of the friction between the tracks of the roller coaster and the actual car and it also has heat because every thing has heat energy no matter what
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.
What are the main energy transfers that happen as a roller coaster cart travels along the track fromthe start of the ride to the end?
Basically the main energy transfers in a Roller Coasters are, Gravitational Potential Energy (PE), Kinetic Energy (KE) and some energy is lost through Heat and Sound.
What is the kinetic energy of a 45.0 kg skater who is skating down a hill on roller blades at a speed of 10.0 m per s?
kinetic_energy = ½mv² = ½ × 45 kg × (10 m/s)² = 2250 Joules.
When does a roller coaster increase kinetic energy?
The roller coaster increases kinetic energy when its velocity is increasing.

Can you use roller blades for figure skating?
If you are crazy enough to try, I don't see why not :)
Where is the kinetic energy the highest on a roller coaster?
The cars of a roller coaster reach their maximum kinetic energy when at the bottom of their path.
In energy transformations when a roller coaster is at the top of the hill the kinetic energy is?
Kinetic energy comes from movement. If the roller coaster is moving at the top of the hill, it has kinetic energy. if the rollercoaster isn't moving then it has potential energy.
Does carousel roller skating rink have roller blades?
If you are talking about the one in Massachusetts, in the Whitman area then yes. They are black and orange. Just saying.
What energy is in a roller coaster?
Potential energy is used when going up hill on a roller coaster. When it starts gong down the potential energy is converted to kinetic energy.
What is an example kinetic energy?
a roller coster
Does the roller coaster need kinetic energy to move down the tracks?
If its moving it has kinetic energy
What type of energy does roller coasters use?
kinetic
What type of energy roller coaster use?
kinetic
