[QUOTE="aosome23, post: 4839927, member: 493498"] [h2]Homework Statement [/h2] Find the force to stop a 5kg ball at 20m/s instantly. Dont take in account resistance. [h2]Homework Equations[/h2] kinetic energy = 0.5*mass*velocity^2 Energy = force * distance force = energy / distance [h2]The Attempt at a Solution[/h2] 0.5 * 5kg * 20m/s^2 = 1000J 1000J / 0 = ? As seen it does not work if you want to find the force to counter it exactly... What am I doing wrong? Thanks [/QUOTE]
