IP You want to nail a 2.4kg- board onto the wall of a barn. To position the board before nailing, you push it against the wall with a horizontal force to keep it from sliding to the ground
What happens to the force of static friction if you push against the wall with a force greater than that found in part A? Will it
A)The force of static friction will increase.
B)The force of static friction will decrease.
C)The force of static friction will be the same.
and in partA i got 32 N
now i am confused because i thought the static friction would decrease. I plugged it back in to the problme and i got a lower number but that was wrong.
never minded i got it. it will remain the same
