Which formula can be used to find velocity if kinetic energy and mass are known?

V = √(2K.E/m) where v is the velocity, K.E is the kinetic energy and m is the mass.

Kinetic energy is the energy possessed by a body when in motion. It is calculated by the formula, K.E = 1/2 MV² , where m is the mass of the body, and v is the velocity of the body.

To get Velocity from the formula, we make V the subject of the formula, such that;

K.E = 1/2mv², multiplying both side by 2;

2 k.e = mv²; then we divide both side by m.

v² = 2k.e/m; then we get the square root on both side;

v = √(2k.e/m)
