For a constant force, suppose the duration of impact on an object is doubled. How much is the impulse increased? How much is the resulting change in momentum increased?

Both are doubled.

Explanation:

Impulse is force*time. Also, impulse is change in momentum. Therefore,
#"force*time" = "change in momentum"#

If the force is constant while the time of impact is doubled, the impulse is doubled and the resulting change in momentum is doubled.

I hope this helps,
Steve
