How fast does a 3000kg elephant have to go to have the same kinetic energy of a 65 kg skater traveling at 10 meters per second?
Lets list out the variables, the skater has a mass of 65kg, or m1 and a velocity of 10 m/s , or v1 which gives the value for its kenetic energy k1 to be
K= .5 mv^2 = .5 (65)(10^2)= 3250 J
We set that number equal to the new equasion for the elephant
3250= .5mv^2 = .5(3000)v^2
and we solve for v getting an answer of 1.47 m/s

What is an example of kinetic energy as it applies to a vehicle?
When a vehicle is moving, it possesses kinetic energy. For instance, a car traveling down the highway has kinetic energy due to its motion. This energy is a result of the vehicle's mass and velocity.
What is kinetic head?
"Kinetic head" is not a common term in physics or engineering. It may refer to the kinetic energy of an object traveling with a certain velocity or the energy associated with the movement of fluid in a system. Clarification would be needed to provide a more specific answer.
What If you have four balls all traveling at 5 meters per second which one has the most kinetic energy?
All four balls would have the same kinetic energy since kinetic energy is determined by both the mass and velocity of the object. If all four balls have the same mass and velocity, their kinetic energy would be equal.
Why is there kinetic energy?
because there is kinetic energy.
When kinetic energy increases what happens to the mass and velocity?
Kinetic energy of a mass is directly proportional to two variables: its mass and speed. Many mistake kinetic energy as being proportional to mass and velocity; it is, in fact, mass and speed. (With all technicalities aside, the speed is the factor that matters in computing kinetic energy of an object or a mass). Kinetic Energy = 0.5mv2 (m = mass and v = speed of the mass) Therefore, if the speed of the object increases, the kinetic energy increases. If the speed of the object decreases, the kinetic energy decreases. Similarly, if the mass of the object increases while traveling, its kinetic energy increases. If the mass of the object decreases, the kinetic energy decreases. All has to do with the directly proportional relationship between the two variables and the kinetic energy.
What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
If two bicycles have the same mass but one is traveling at 10 ms and the other is traveling at 15 ms which has more kinetic energy?
The bicycle traveling at 15 m/s has more kinetic energy because kinetic energy is proportional to the square of the velocity. Since the mass is the same for both bicycles, the one traveling faster will have a greater kinetic energy.
Which car has the most kinetic energy?
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.
What type of energy a car is traveling 45 mph have?
A car traveling at 45 mph has kinetic energy, which is the energy of motion. As the car moves, its speed and mass contribute to its kinetic energy. This energy is what enables the car to perform work and overcome resistance while in motion.
Does kinetic energy decrease when traveling up hill?
Yes, kinetic energy decreases when traveling uphill because some of the energy is converted into potential energy to overcome gravity. This results in a decrease in the speed of the object.
Why does a train have more kinetic energy than a car traveling at the same speed?
A train has more kinetic energy than a car traveling at the same speed because the train has significantly more mass. Kinetic energy is directly proportional to an object's mass - the more mass an object has, the more kinetic energy it will possess at a given speed.
What is an example of kinetic energy as it applies to a vehicle?
When a vehicle is moving, it possesses kinetic energy. For instance, a car traveling down the highway has kinetic energy due to its motion. This energy is a result of the vehicle's mass and velocity.
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 kind of kinetic energy does a car and bus traveling at 60 mph have?
Kinetic energy is given by 1/2 M x V2, that is one half mass x velocity squared
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.
