Homework Statement



Ok so 1000(5.556 m/s – 0 m/s)/0.055 = 101018 Newton’s which is a unit of force. We know the force was applied for 1 foot of travel (.3048meters)

Homework Equations


So the incorrect conversion would be to multiply by .3048 to get 30790 Newton meters per second. I am missing the time component

The Attempt at a Solution


Do I need to divide 1 by 0.055seconds and than multiply that number by 30790? Any help would be appreciated I am baffled. Thanks

It's not clear what you are talking about here. Some of the units have been omitted, which muddies the water further. 1000 what? 0.055 what? You've jumped into the middle of something here; we just don't know what.

Ya I definitely stepped in it. Sorry. 1000 is the weight in kilograms, and 0.055 is the time in seconds

Mass * velocity = momentum

momentum / time = ?

Ok I think that helps, Thanks
 
Hi Paulhook. Welcome to Physics Forums.
