Do I have to divide 5.0 by 2.0 in order to get the momentum or multiply?

if it acted for one second, the answer would be 5 N m West

for two seconds it is TWICE, not half.

**Damon**, Wednesday, April 21, 2010 at 7:55pmF = rate of change of momentum

F = change in momentum / change in time

change of momentum = F * change in time
