Answer:

If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. ... A boxer moves away from a punch, extending the time of impact and lessening the force

Answer:

A small force could causes the same change in momentum, but it would have to act for a much longer time.bending your knees decreases the time of the impact,thus decreasing the force. to determine the change in momentum, substitute the values for mass and the initial and final velocities...
