Calculating Momentum Change with an Impulse of 25 N~s

[you too]

if an impulse of 25 N~s results, how would one describe the change in momentum?

how is that number related or indicative of the change in momentum?

i could be way off. that's likely. thanks.

Impulse is change in momentum.

momentum-impulse theorem says:
delta p = impulse;
if impulse is 25 it means that there is a change in momentum, i.e. momentum is not conserved...final momentum is greater than initial...that's all I know...I hope it helped.

so if it asks what change in momentum does the cart undergo, i write 25 N~s? i thought momentum was measured in kg~m/s.

$$Ft=m\Delta v$$

If you calculate what a Newton is in primary units, you'll see that $Ns=kg\,m/s$

is that question for me?

Ft is impulse and mv is momentum, and impulse = change in momentum, or maybe it wasn't a question for me?

Sorry, I mixed you up with the OP.

Yes!

geoffjb, it's OK!
