Two people are running a 5 km race and one person is running at a pace of 15 km per hour and while the other is running at a pace of 12 km per hour so Which runner has more kinetic energy and why?

We can't tell, because we don't know the masses (weights) of the runners.
Kinetic energy of any object is (1/2 of mass) times (square of speed).
Since the kinetic energy depends on mass as well as speed, it's very easy for a slower object
to have more kinetic energy than a faster object, if it has more mass.
If the runners have equal mass, then the guy covering 15 km per hour has more KE.
But remember: A truck that's barely inching along up the hill has a lot more KE than
the speeding bicycle that passes it.

Is bubble a verb?
Bubble is a noun. (Noun- person, place, or thing) A verb is an action. EX: running, jumping, running, smiling, talking, ect.
If you were running a race, and you passed the person in second place, what place would you be in now?
If you passed him after you crossed the finish line, he finished 2nd so you're in the 3rd place now. Or you may have passed him while you were running the other way, you were not in the race at all, then hopefully you would be in the place you were running to. The simplest answer is that when you passed the person in second place, you would now be in second place yourself.
What is the kinetic energy of a 60.5 gram bullet moving at a velocity of 273 meters per second?
KE = 1/2 M V2 = (0.5) x (0.0605) x (273)2 = 2,254.5 joules (rounded)That's considerable KE ! It's roughly the same as a 220-pound man moving at 15 mph.That helps me understand how a bullet can knock a big person down, not to mentiondoing some damage to his infrastructure..
If each OF seven persons in a group shakes hands with each of the other six persons then a total of forty two handshakes occurs?
The correct answer is 21. The first person shakes hands with the other 6 people. The second person shakes hands with 5 people because they already shook hands with the first person. The third person shakes hands with 4 people because they already shook hands with the first and second person. The fourth person shakes hands with 3 people because they already shook hands with the first, second, and third. The fifth person shakes hands with 2 people because they already shook hands with the first, second, third, and fourth person. The sixth person shakes hands with the seventh person because the rest have already shaken hands with them. The seventh person doesn't have anyone else to shake hands with. So the total would be 21...

Therefore the answer is 21 handshakes.
A person running around a track demonstrates energy?
kinetic
What form of energy when person running?
Chemical potential energy of the body is converted to kinetic energy.
What is Kinect energy?
The kinetic energy is the energy an object has because it has motion or movement. For example, a person running is an example of kinetic energy because they are moving/ have motion.
What is an non example for potential energy?
A person running is not an example of potential energy. it is an example of kinetic energy.
What is the main difference between potential and kinetic?
The main difference between potential and kinetic energy is that potential is energy that has the opportunity to become kinetic. Kinetic energy is the energy of motion.examples of potential energy- a spring being squeezed; When you are at the top of the diving board getting ready to dive; winding up before you throw a pitch (in softball); etc.examples of kinetic energy- a person running; a car speeding; falling down the stairs; etc.
Who has the most kinetic energy a person running in a race or a plane in flight?
A plane in flight. It has both the greater mass, and the greater speed.
What other things can energy do?
There are three types of energy: Mechanical, Kinetic, and Potential. Kinetic is defined as energy in motion (person running, ball rolling). Potential energy is energy that is to be used and about to happen (food, book about to fall off a table). Mechanical energy is both Kinetic and Potential energy (roller coasters are a great example). The law of conservation of energy states that 'Energy cannot be created or destroyed, but converted from kinds of energy'. Energy can be converted.
What form energy is used when a person pushes a wooden block across the floor?
Friction is produced and kinetic energy is used
One person weighs 600 newtons and the other weighs 555 newtons Which person has more kinetic energy?
Kinetic energy measures the amount of energy a person has as they are in motion. In this instance, the person who weighs 600 Newtons has more energy.
What kind of energy is displayed when a person is jogging?
kinetic
What energy is used when a person is falling from a building?
It is kinetic. Someone/something going from its gravitational (not moving) energy to then moving, creates kinetic energy, because it goes from stationary to moving. GRAVITATIONAL ------> KINETIC
How does a yo-yo transer potential energy to kinetic energy and back to potential energy as it moves up and down the string?
When the yo-yo is being held in the person's hand, it has maxium potential energy, and zero kinetic energy. When the yo-yo drops on the string from the person's hand, it's velocity increases due to the acceleration due to gravity, increasing kinetic energy and reducing potential energy. When the yo-yo is at its greatest distance from the person's hand, it has maximum kinetic energy, and zero potential energy. When the yo-yo moves back up the string, its kinetic energy decreases and its potential energy increases. Once the yo-yo is back in the person's hand, it again has maximum potential energy, and zero kinetic energy.
