Define Kinetic Energy. Write expression for Kinetic Energy.A force of 12N acts on an object of mass of 4kg in the state of rest for 3s. Calculate the kinetic energy acquired by the object |

Answer» n that, MASS = 4kg Time = 3s Velocity = ? Kinetic Energy = ? Let's calculate velocity, F = ma { a = v/t } F = mv/t 12 = 4×v/3 v = 9 m/s Let's calculate Kinetic energy = 1/2mv^2 1/2×4×9×9 162 J. Therefore, the Kinetic energy is 162 J. Hope this helps you.
