When two people of the same mass are running a 5-k race. One person is running at a pace of 15 kmh while the other is running at a pace of 12 kmh. Which runner has more kinetic energy Why?

The one going faster - because KE = 1/2 m v squared.

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.
How can you increase the amount of kinetic energy in a small ball of clay you are throwing at a person?
you can increase the amount of kinetic energy by increasing the mass and the velocity..
What is the kinetic energy of a person on top of a tower e equals with a potential energy of 15000 joules?
(assuming no air resistance)potential energy translated to kinetic energy.you need some numbers in:potential energy = m*g*h = 15 000 jsay m = 100 kgsay g = 10 m/s^2 (approximation)then h = 15 000 / (100*10) = 15 metresso100 kg after falling 15 metres will have kinetic energy = 15 000 joulesKE = 0.5 * m * v^2so velocity) at base of tower :v =square root (15 000 / (0.5 * 100))v = 17.32 metres / secondso , potential energy lost = kinetic energy gained.
Why does a person's kinetic energy decreases as they enters water?
Yes , because when you enter water, it's density is 1,000kg so it makes it harder to walk and run.
Which energy might correspond to the KE of a person riding a bicycle on a road?
Kinetic energy is energy related to movement. The formula is KE = (1/2) mv2, where "v" is the speed, and "m" is the mass. If the mass is in kilograms and the speed in meters/second, the energy will be in joules.
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.
