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)

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
