What is the kinetic energy of a 35kg child running at a speed of 1 m's across the yard to tag his friend?

Kinetic Energy = 1/2 * mass * velocity squared
KE = 1/2mV2
KE = 1/2(35 kg)(1 m/s)2
= 18 Joules

Where can I find information on lunar eclipse running shoes?
They are a Really good model of trainer and your friend is correct. You can find out more information on the following website http://www.triradar.com/gear/nike-lunar-eclipse-running-shoes/
What are starches and sugars that provide energy?
Carbohydrates are the starches and sugars that provide energy. Starches are complex carbohydrates that give you extended energy and sugars are simple carbohydrates that give you a quick burst of energy.
Who do you call after running out of gas in the middle of the highway?
If you have ran out of gas in the middle of the highway, it is best to call AAA. If you do not have an AAA membership, call a family member or friend to help you by picking up some fuel and bringing it to you.
Effect of honey with cold water on human body?
I think that the body needs lots of energy to digest honey, and it needs a lot of energy to warm cold water. This puts lots of pressure on your body, and you may die. Source: My best friend died from eating honey and drinking cold water.
What is the most powerful erosive force on earth?
Running Water
You watch your friend take off in a jet plane and you comment on the kinetic energy she has acquired But she says she has no such increaze in kinetic energy Who is correct?
You are correct. When the jet moved, she moved with it. If she was moving faster than she was before, then she gained kinetic energy. She lost that kinetic energy when the plane touched down and came to a stop.
A friend says that in a mixture of gas in thermal equilibrium that the molecules have the same average kinetic energy Do you agree or disagree?
agree.
Eddie tosses his phone up to his friend's window which is 4 m above the ground. What energy conversion takes place with respect to the phone?
Kinetic energy to gravitational potential energy
Imagine that you drop a ball it bounces a few times and then it stops your friend says that the energy that the ball had is gone where did the energy go?
Some of the energy has converted into heat energy because of the friction, the kinetic energy is gone, but there is potential energy. Also, some of the energy has converted into sound energy from the basketball bouncing. Your friend is wrong because there is still energy like kinetic energy, energy cannot disappear it gets converted.
How do you use the across in a sentence?
My friend lives across the street from me, so we usually hang out.
What if your friend says that the law of conservation of momentum violated when a ball rolls down a hill and gain momentum what do you say?
it could be said that since potential energy (mgh) is lost at the exact rate kinetic energy (ke) is gained, that energy is translated into another form since force applied (gravity) over time then impulse applied and increase of momentum
My best guy friend has a gf but the other night we were watching a movie together and he was lightly running his hands across my lower back we had a fight the day before what was he doing?
he should forgive his self. and let him apologize!
How is kinectic and ppotential energy different?
In the world of science we do not understand many ungodly things you my friend need to listen... Kinetic energy is a source of a moving energy; like a ball rolling or you throwing a pen using force (also known as work) Potential energy as we call it is stored energy like a ball NOT rolling just sitting there. so kinetic is moving energy and potential is non moving or stored energy! Wow!! HEY THAT IS COOL!!! SAY THAT RIGHT NOW! made by a genius in her fifth grade lab! if you are an older person (passed collage) then you would lose "Are you smarter than a fifth grader" because I am!!! you bonk, you snarky gadzook, you homosapien... ha ha those words all mean human!!!!
What was Terry Fox's friend's name that drove beside him while we were running?
Doug, he drove beside him while he was running
Does niall live in Ireland now?
I think he lives one street across from my friend Hannah Cox's friend
What if your mistress likes to be just a friend no more for your next relations?
Well then the ball is in your court is she your friend because she comes across or is she your friend wether she does or not. The answer must be simple to you.
