1.)To reduce the force of impact you could
a)Extend the duration of the time of impact
b)Decrease the duration of the time of impact
c)Increase the mass of the moving object
=d)None of the above
2.)What happens when you lengthen the duration of impact?
=a)You reduce the force of the impact b)You increase the force of the impact
c)You do not affect the force of impact
on the first, I suspect you are dealing with momentum and impulse. Given an impulse, avgforce*time=impulse, so if one increases time of impact, the avg force decreases.
