newtonian mechanics - velocity, mass and force


Is there an equation linking velocity, mass and force? I want to find the maximum force that an object of any given mass could exert. Assuming, the object with the given velocity stops dead in an instant, I thought of using F=ma but there is no time frame for the slowing down of the object since it's instant. Thank you



Answer



Change in momentum $\Delta m v$ is equal to impulse $F \Delta t$, the force multiplied with the time that force acts on the body.


So to stop in an instant, the force is very large.
