How fast does a 75 kg person have to run to have 360000 Joules of energy?

The idea is to use the standard formula for kinetic energy:
KE = (1/2)mv2
Replace the variables you know, and solve the equation for the variable you don't know (in this case, "v", the speed).

What is the watts equivalent of 231000 joules?
231,000 joules is an amount of energy, while watts are a measure of how fast energy is used or converted. 231,000 joules could be used by 1 watt running for 231,000 seconds, or 231 watts running for 1000 seconds, etc. Energy = power x time, so 1000 watts for 231 seconds is an amount of energy equal to 231,000 joules.
How many watts is needed to melt one pound of aluminum?
How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
How many watts are 4680000000joules?
Watts are a measure of power, Joules are a measure of energy. The energy is equal to the power times the time. So if you have a power of 5 watts running for 7 seconds, that is 5x7 Joules of energy, or 35 Joules. Looked at another way, power measures how fast energy is converted. So 35 Joules converted in 7 seconds would be 5 watts of power, but it would need 35 watts to convert that energy in 1 second.
What is the between work and power?
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.
The amount of energy an object contains and how fast the particles of matter move is?
Kinetic energy = 1/2mv2, where kinetic energy is measured in Joules, mass in grams, and velocity in m/s.
How fast will an object be moving if its kinetic energy is 300 joules and has a mass of 0.05 kilograms?
The object's velocity will be 109.54 meters per second.
How fast in mph is 100 yards per second?
There are 3600 seconds in one hour. Therefore, 100 yards per second is equal to 100 x 3600 = 360000 yards per hour. There are 1760 yards in one mile. Therefore, 360000 yards per hour is equal to 360000/1760 = 204.54 recurring (that is, 204.545454...) miles per hour.
How do you convert Mega Joules to Joules?
You can't convert them directly, because they measure different things. The unit for energy is the Joule. Power means how fast energy is transferred; it is measured in Joules/second, also called Watts.
How many joules of kenetic energy does 1 kg book have when it is tossed across the room at a speed of 2 miles per second?
Needs conversion. 2 m/s (1609 meters/1 mile) = 3218 meters per second ( fast!! ) Kinetic Energy = 1/2(mass)(velocity in meters per second)^2 KE = 1/2(1 kg)(3218 m/s)^2 = 5177762 Joules ( 5.2 X 10^6 Joules ) --------------------------------------------------
What should a person eat if he wants fast supply of energy?
He should eat banana and/or honey
Why can't i win at soccer?
maybe your strategies dont work for your team or you run out of energy too fast. it depends from person person
What is electrical measurement?
Electric power (how fast energy is being converted into or out of electrical energy) is measured in Watts. Electrical energy is measured in Joules. i Watt for 1 second is 1 Joule. 1000 Watts for 3600 seconds is 3.6 Megajoules, also known as a kilowatt-hour or a Unit of electrical energy.
