Not an actual HW problem, but related to alot of probs i'm doing.
Lets say a hand pushes a block across a surface (with friction).
You take pic of 2 timepoints
1) when hand pushes block
2) After hand has let go and block is slowing due to friction
Now when I draw the FBD for situation #2, I am confused about the horizontal forces. (i know that vertical forces cancel)
I know that 1 vector (kinetic friction) will point opposite the motion.
BUT: Is there a forces that goes in the direction of motion???
If there isn't, then how is the block moving??
If there is, then what force could that be, seeing as the hand is no longer in contact with the block??
Thanks in advance for any explanation!
