If one knows only the constant resultant force acting on an object and the time during which this force acts

Respuesta :

Explanation:

  • We know that Newton's second law of motion gives the measure of external force acting on an object. It says that the rate of change of linear momentum of an object is directly proportional to the external applied force. It is given by :

[tex]F=\dfrac{\Delta p}{\Delta t}[/tex]

Since, p = mv m is mass and v is velocity.

[tex]F=\dfrac{m(v-u)}{ t}\\\\F\times t=m(v-u)[/tex]

So, if one knows only the constant resultant force acting on an object and the time during which this force acts, one can determine the change in momentum of the impulse.
