Kinetic Energy= 1/2 M V2 =
1/2 (2.04 x 104) x (80 km/hr x 1,000m/km x 1 hr/3,600 sec)2 =
5,037,037 joules = 5,037 kilojoules

What energy is in a traveling bullet?
kinetic energy
What sort of energy does running use up?
running uses kinetic energy. * kinetic energy:is the energy produced by a moving object or when someone is moving. * runnung needs 60 kilojoules of energy for every minute you run.
What type of energy a car is traveling 45 mph have?
Kinetic Energy
What is the kinetic energy of a 22500 lb truck traveling 55 mph?
The kinetic energy of a 22500 lb truck traveling 55 mph is 1/2mv2 is 3084.808kJ.
Is a race-car traveling at its maximum speed potential or kinetic energy?
A car is not energy; it may have energy. The energy related to movement is called kinetic energy.
What is the kinetic energy of a bicyclewith mass 10 kg traveling at a velocity of 3ms?
The bike's kinetic energy is 45 joules.
Why does a train have more kinetic energy than a car traveling at the same speed?
Kinetic energy also depends on mass.
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
What has greater kinetic energy a car traveling at 35 miles per hour or a car traveling at 50 miles per hour?
Kinetic Energy is defined as the energy associated with motion. This is in contrast to potential energy which is associated with an entity's energy at rest, and it's potential for motion. Kinetic Energy can be calculated using this formula: KE = 0.5*Mass*Velocity^2, where KE = Kinetic Energy It is apparent by the formula that the same car traveling at a higher speed will have a greater kinetic energy than it does when traveling at a lower speed. Therefore, when the car travels at 50 mi/hr it has a higher kinetic energy than when it travels at 35 mi/hr. Let me just note that if we were talking about two different cars then we'd have to consider the weights of the cars.
Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
What type of energy does a car traveling 45 ms contain?
The energy related to movement is called kinetic energy.
A 1009.6 kilogram car has 3040.7 jules of kinetic energy how fast is it traveling?
Use the formula for kinetic energy: KE = (1/2)mv2. Replace the numbers you know (mass, and kinetic energy), and solve.
