Kinetic energy = (1/2) (mass) (velocity squared)

Divide each side
by (velocity squared/2): Mass in kg = ( 2 x energy in joules) / (velocity in m/s) squared

What is 75kg in joules?

Mass is measured in kilograms, not in joules. Joules are a unit of energy. To calculate the energy of a 75kg mass, you would need additional information such as the velocity or height it is at.


How many joule is 300 fps?

To convert feet per second (fps) to joules, you need the mass of the projectile. The formula to calculate joules is 0.5 * mass * velocity^2. Without knowing the mass of the projectile, it is not possible to accurately calculate joules based solely on the velocity of 300 fps.


How do you find velocity when given mass and momentum?

To find velocity when given mass and momentum, you can use the formula: velocity momentum / mass. Simply divide the momentum by the mass to calculate the velocity.


How do you calculate force when mass and velocity are given?

Force equals the mass times the rate of change of the velocity.


How do you find the speed given joules and mass?

Use the formula for Kinetic Energy (KE), which is the energy due to the motion of an object. KE = (1/2) * (mass) * (velocity)2 where KE is in joules, mass is in kg, and velocity (or speed) would be in meters/sec...Just substitute the appropriate numbers, rearrange and solve for velocity


How do you find mass if you given velocity?

That's not enough information. You need some additional information to calculate the mass.


Mass is 145g and velocity is 25ms Find the answer using kinetic energy formula?

Kinetic energy is 0.45 joules using the formula Ek = ½ x mv2


How do you calculate power when given speed acceleration weight and distance?

Power is equal to Force times velocity; P=Fv. You are given the 'speed', which I assume to be velocity. You also have acceleration. In order to find F, you need first to find the mass, which you can calculate from the weight, Fg, by dividing by the acceleration due to gravity, 9.8. You then have the mass. From here, multiply mass times acceleration times the velocity.


How to find velocity with mass and momentum?

To find velocity with mass and momentum, you can use the formula: velocity momentum / mass. Simply divide the momentum by the mass to calculate the velocity.


How to find potential energy when only mass and velocity time is given?

To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.


How can calculate recoil velocity of gun?

The recoil velocity of a gun can be calculated using the principle of conservation of momentum. The formula to calculate the recoil velocity is: Recoil velocity = (mass of bullet * velocity of bullet) / mass of gun. This formula takes into account the mass of the bullet, the velocity of the bullet, and the mass of the gun.


What is the electron velocity formula used to calculate the speed of electrons in a given system?

The formula used to calculate the speed of electrons in a given system is v e/m, where v represents the velocity of the electron, e is the charge of the electron, and m is the mass of the electron.
