What is a car's kinetic energy if it is 1500 kilograms and is moving at a speed of ten miles per second?
Are you sure you mean 10 miles per second? That is a speed of 36,000 mph (unless you are referring to the speed of the car relative to the orbit of the earth as the earth orbits the sun, but that is approx 19 miles per second).
I think you mean 10 metres per second (as you've used a metric measure for the mass of the car).
kinetic energy = ½ × mass × velocity²
→ KE = ½ × 1500 kg × (10 m/s)²
→ KE = 75000 kgm²/s² = 75000 Joules = 75 kJ
What else can I help you with?
What is the kinetic energy of a car with the mass of 2500 kilograms moving at 35 meters per second?
Kinetic Energy = 1/2 * mass(kg) * Velocity(m/s) squared KE = 1/2mV^2 KE =1/2(2500 kg)(35 m/s)^2 = 1531250 Joules better expressed as 1.5 X 10^6 Joules
How do you show mathematically why a small increase in your vehicle's speed results in a tremendous increase in your vehicles kinetic energy?
The kinetic energy of a vehicle, of mass m kilograms and travelling at velocity v metres per second, is 1/2*m*v2.Using calculus, d(ke)/dv = m*v.That is, the kinetic energy (ke) increases by the product of the mass and the velocity. Whether or not that can be considered "tremendous" is another matter.The kinetic energy of a vehicle, of mass m kilograms and travelling at velocity v metres per second, is 1/2*m*v2.Using calculus, d(ke)/dv = m*v.That is, the kinetic energy (ke) increases by the product of the mass and the velocity.

How much work has to be done on a 5 kg sled to increase its speed from 10 m s to 15 m s?
Work is simply a transfer of energy. Calculate the kinetic energy for both speeds, then calculate the difference. The formula for kinetic energy is KE = (1/2)mv2. If the mass is in kilograms, and the velocity (or speed) is in meter/second, the energy is in Joule.
How much work must be done on a 10 kilograms bicycle to increase its speed from 2 meters per second to 3 meters pe second?
When the bike is moving at 2 m/s, its kinetic energy is (1/2 m v2) = (5 x 4) = 20 joules.When it's moving at 3 m/s, its kinetic energy is (1/2 m v2) = (5 x 9) = 45 joules.The difference between initial KE and final KE is (45 - 20) = 25 joules.That's how much work you have to do on it in order to increase its KE.
How much kinetic energy does a runner have when dashing at 7 miles per second?
7 miles per second? Don't you mean 7 meters per second?
What is the mathmetical formula for kinetic energy?
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2
Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?
The object with the mass of 4 kilograms that was lifted at a rate of 3 meters per second would have more kinetic energy. Kinetic energy depends on both mass and velocity, so the increased mass more than compensated for the lower velocity compared to the 2-kilogram object.
What is the energy of a system by virtue of its motion?
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.
What kinetic energy does a ceiling fan have?
The kinetic energy of a ceiling fan depends on its mass and the speed at which it is spinning. The formula for kinetic energy is 0.5 * mass * velocity^2, where mass is in kilograms and velocity is in meters per second. Generally, the kinetic energy of a ceiling fan is relatively low compared to other moving objects.
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 the kinetic energy of a Toyota Prius?
Kinetic energy is (1/2) x mass times velocity2. If the car is at rest, its kinetic energy is zero. If it is moving, look up its mass in kilograms, or do a reasonable estimate; assume a reasonable speed, in meters per second (for example, 20 meter per second; this is equivalent to 72 km/hour), and plug it into the above formula. The result will be in Joule.
What is the kinetic energy of a 8.47E plus 4 gram person moving at a velocity of 24.9 meters per second?
The kinetic energy of the person can be calculated using the formula: KE = 0.5 * mass * velocity^2. First convert the mass to kilograms (1 gram = 0.001 kg), then plug in the values to find the kinetic energy. The result will be in Joules.
If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a kinetic energy of 4500 Joules. what is its kinetic energy when the velocity is 32 meters per second?
Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.
What is the kinetic energy of a 4 kilograms object moving at 6 meters per second?
KE = 1/2 * mass * velocity squared KE = 1/2mV2 KE = 1/2(4 kilograms )(6 m/s )2 = 72 Joules ---------------
How factors are used to calculate the kinetic energy of an object?
KE = (1/2)mv2 where m = mass (in kilograms), and v = velocity (in meters/second) this gives you the kinetic energy in units of Joules
How do you compare kinetic energies on things that move?
Kinetic energy = (1/2)*mass*(speed)^2 where, in metric units, mass is in kilograms, speed is in meters/second, and kinetic energy is in Joules. So, you need to know the mass and the speed of the things.
How much kinetic energy does an electron traveling in free space at 32415.926535 ms have?
You are supposed to use the formula for kinetic energy. As a reminder, the formula is (1/2)mv2. If the speed is in meters per second, and the mass in kilograms, the energy will be in joules.
