Physics (Algebra Bit)
thanks for help on other question =]

Physics (Algebra Bit)
I still need help on my other question as well... A runner hopes to complete the 10,000 m run in less than 30.0 min. AFter running at constant speed exactly 27.0 min there are still 1100 m to go. The runner must then accelerate at .20 s^-2 m for how many seconds in order to ac...

ok for the applied force for (a) on the bottom block I got 83 N not sure if it's right... for the applied force in (b) wouldn't it be the same... I'm confused... Can you check my answer for (c)

Physics
can you check my answer for (c)

Physics
Sense this problem 32 the answer isn't in the back =[

Physics
ok part (b) 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 ...

Physics
also is the talbe frictionless or not I couldn't understand by the way it was worded

Physics
hmmmmmm interesting THANKS YOU

Physics
wouldn't it have a zero acceleration sense it's suppose to not be moving

Physics
Were did 4.5 s^-2 m come from???
