ahhh ok that makes sense, and no again you helped a lot and now i can know the why behind it so it really helps

It says to find the resulting force on the impact

thank you so so much for all your help I feel like I get such a better understanding and can go on and do my other hw! Thank you!

to the left?

I'm not quite sure how to make it not negative

N ??

No it shouldn't shoot haha, I wrote down in my notebook that units should be N/ S does that seem right?

yes meant to put a negative so would it be F= -40000

F=40000 kg m/s

divide! sorry its been a while with math and science for me lol

yay! so subtract 0.5 sec to -20000?

oh! so would the formula be f 0.5 sec=-20000 kg/ms and then do the calculations to it?

thank you for helping me btw

No because I'm trying to find the final force right? So where the heck does the 0.5 sec fit? change of time??

ok. this is getting much clearer I think...haha ok so then the pi would = 20000 kg m/s and pf= 0 m/s therefore it would be -20000 kg m/s for the final momentum?
