∙ 9y agoKinetic Energy; usually calculated using the formula: Ek = 0.5 mv2 Where Ek is the kinetic energy, m is the mass and v is the velocity (speed).
Kinetic energy is calculated using mass and velocity. KE=1/2mv2
Ek = 0.5mv2Kinetic energy equals half times mass times the square of the velocity. Using SI units, mass in kilograms and velocity in metres per second, the energy will be in Joules.
KE=1/2*m*v2whereKE is kinetic energym is the massand V is the velocity
His kinetic energy is 5,688 kilogram-meters.Now you do the calculation, and if you arrive at the same solution,then you'll know that your work is correct.

Use the formula KE = (1/2)mv2 (kinetic energy equals 1/2 times mass times the square of the velocity).Use the formula KE = (1/2)mv2 (kinetic energy equals 1/2 times mass times the square of the velocity).Use the formula KE = (1/2)mv2 (kinetic energy equals 1/2 times mass times the square of the velocity).Use the formula KE = (1/2)mv2 (kinetic energy equals 1/2 times mass times the square of the velocity).
when using energy use the kinetic energy equation for change KE = .5(M)(Vf^2 - Vo^2) M = mass Vf = fianal velocity Vo = initial velocity
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.

Calculate the initial potential energy (PE = mgh). Assume that all of this gets converted to kinetic energy, and solve for velocity (KE = 0.5 mv2).
This question is all about kinetic energy. Kinetic Energy = 0.5 * mass * velocity^2 Firstly we must assume that no energy is lost to heat and sound, so that kinetic energy is constant throughout the contact. The initial kinetic energy is all in the 2kg metal ball. Using the above formula we find that the energy is 0.5 * 2 * 3^2 = 0.5 * 2 * 9 = 9 J The final kinetic energy must be the same (because of our assumption). The metal ball has a kinetic energy of 0.5 * 2 * 1^2 = 1 J, so the wooden ball must have the remainder, which is 8 J. 8 = 0.5 * 1 * velocity^2 velocity^2 = 16 velocity = square root of 16 velocity = 4 m/s
