Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.

What is the kinetic energy of the jeepney?
The kinetic energy of a jeepney depends on its mass and velocity. The kinetic energy equation is KE = 0.5 * mass * velocity^2. Given the mass and velocity of the jeepney, the kinetic energy can be calculated using this formula.
If the kinetic energy of a football player running at 8.1 ms is 3610 J what is the mass of that player?
The kinetic energy of an object is given by the formula KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass, and v is the velocity of the object. In this case, with KE = 3610 J and v = 8.1 m/s, you can rearrange the formula to solve for the mass m. Substituting the values given, you can find the mass of the football player.
How can two objects have the same amount of kinetic energy?
Two objects can have the same amount of kinetic energy if they have the same mass and velocity. Kinetic energy is given by the formula KE = 0.5 * mass * velocity^2, so if both objects have the same mass and velocity, they will have the same kinetic energy.

As the mass of an object moving at a given speed decreases its kinetic energy does what?
As the mass of an object moving at a given speed decreases, its kinetic energy also decreases proportionally. Kinetic energy is directly proportional to the mass of the object, so a decrease in mass will result in a decrease in kinetic energy.

How does mass and speed relate to kinetic power?
Kinetic energy (not power) is given by 1/2 x Mass x Velocity2
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 velocity does 1kg object have when it skinetic energy is 1j?
The formula for kinetic energy is KE = 0.5 * m * v^2, where m is the mass and v is the velocity. Given that the kinetic energy is 1 J and the mass is 1 kg, we can rearrange the formula to solve for v. Solving for v, we get v ≈ 2 m/s.
What would be the skaters speed if all the potential energy could be converted into kinetic energy?
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).
