a force of 12N acts on an object of mass 4kg in the state of rest for 3s calculate the kinetic energy acquired by the object |
|
Answer» n that, Force = 12N 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.
