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 )

How to calculate rate of energy transfer in Joules per second or Joules per minute?
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".
What is the rate at which work is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
What equals 4.5?
It is equal to 4.5 joules per second. "Watt" means how quickly energy is generated, consumed, or converted.
A human heart consumes about 1 joule per heartbeat about how many joules of energy must food furnish to a person each day to supply this energy?
The energy required is roughly 3600 seconds/hour x24 hours/day x1 joule/second=86400 joules /day.
How are watts and joules related?
This is a very good question. A joule is a unit of energy, and a watt is a unit of power. Power is the rate at which energy is converted from potenital to kinetic energy. So power is some quantity of energy divided by some unit of time. In the SI system, a watt is equal to 1 joule per second. Real life example. A 60W lightbulb uses 60 joules of energy every second. Hope this helps!
What are the units for kenetic energy?
The units for kinetic energy are Joules (J), which is the same unit as work and energy.
What is the energy used in one second when a bulb have 40Watts.?
The energy used by a 40W bulb in one second is 40 Joules. This is because power is defined as the rate at which energy is transferred or converted, so if the bulb consumes 40W of power in one second, it uses 40 Joules of energy in that time period.
How many joules of light energy are in 1440 watts of electrical energy?
To calculate the energy in joules, you can use the formula: energy (joules) = power (watts) × time (seconds). If you have 1440 watts of electrical power and want to calculate the energy in joules for a specific time period, you would need to know the time duration in seconds.
How much energy does an 11watts bulb use per second?
An 11-watt bulb uses 11 joules of energy per second.
What is the energy used every second known as?
Energy / time is known as power. In SI units, time is measured in seconds, energy in joules; the unit for joules / second has the special name watts.
How to calculate rate of energy transfer in Joules per second or Joules per minute?
You can divide any unit of energy by any unit of time; but the standard SI unit is Joules / second, and has the special name "Watt".
What is the power of a light bulb that converts Electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
What is the power of light bulb that converts electrical energy at a rate of 100 joules per second?
100 joules/second = 100 watts.
Is touching a kinetic energy?
Kinetic energy is the energy of motion. Your touching finger has mass and is moving some meters per second, so that motion is kenetic energy.
What is expressed as joules per second?
Power is expressed as joules per second. It is a measure of the rate at which energy is transferred or converted.
How do you convert 1997436.144 Kilojoule to KiloWAtt?
You can't convert from Joules to Watts because Joules is a measure of total energy, and Watts measure energy per second.
What is the rate at which what is done?
Work is energy, measured in joules. The rate of work, or joules per second, is known as watts, or power.
