Basic Kinetic Energy Formula

Energy_Kinetic = 0.5 * Mass * Velocity²

Where:

Energy_Kinetic : Kinetic Energy in Joules.

Mass : Mass of the object in kilograms.

Velocity: Velocity of the object in m/sec.

Working Backwards to Find Mass

Mass = Energy_Kinetic / (0.5 * Velocity²)

Working Backwards to Find Velocity

Velocity = SQRT (2 * Energy_Kinetic / Mass)
