Impulse = (force) x (length of time the force acts).
Divide each side by 'force' :
Length of time of the impact = (Impulse) / (force) .
To find the time of impact based on impulse and force, use the equation Time = Impulse / Force. This allows you to calculate the duration that a force was exerted on an object. Knowing the impulse and force applied will help you understand how long the force acted on the object.
