Sue was slicing Vidalia onions and her eyes were tearing. a 1.4 g tear drop fell 0.4 m and splattered onto the kitchen counter top. How much momentum did the tar impart to the counter top? (Ignore air resistance,)

momentum of the drop= massX velocity =!.4X2.828 gm.m/s.
= momentum of impact

the time it took for that little tar, I meant tear, to fall was
t=sqrt(2h/g)
then it hit the counter at a speed of
V=at
then it's momentum was
p=mV
Did you say in splattered? So was or was it not an inelastic collision ?

It could be 1.4g x 0.4m = 0.56g/m.
