Physics
Isn't net force x direction = -Ffr sense it's in the left direction then I would get a negative Mu???

Physics
i don't see how to apply Newtons second law to the top block there's a force pointing left the force of static friction is there a force opposing this force pointin in the right direction? How do I find the mininum coefficent of friction

Physics
A 4.0 kg block is stacked on top of a 12.0 kg block, whcih is accelerating along a horizontal table at a = 5.2 s^-2 m. Let Mu k = Mu s = Mu. (a) What mininum coefficent of friction Mu between the two blocks will prevent the 4.0 kg block from sliding off? (b) If Mu is only half...

Physics
ok for drag force c = v^-2 Fgx = (2.639 s^-1 m)^-2 95.5 N Fgx = mg sin theta

Physics
ok for b i got 565 N which was correct with book answer in back

Physics
ok I know this is right I redid it (a) 13.7 m^-1 kg

Physics
for (b) i got -.4172 N ;[

Physics
ok for (a) 13.7 s^-1 kg

Physics
part b ... a velocity of 25 h^-1 km is it constant velocity were there would be no acceleration if so then there would be no net force... so i'm lost

Physics
ok i'm stuck on part (b)
