ok if what ur saying is true, then that would mean Fs and Us are equal, and my acceleration would be 1.. but i think that wouldn't make sense... corret me if I am wrong.
Fs= Us * M*N
Fs= Us *M/mg
Fs=Us/g
Fs=.0713
no i take the Fs and plug it back in right
so now i do this:
Fs=Us*n
Fs/Us=n
.0713/.70=.101
n=.101
so that would mean since N=.101
acceleration is also equal .101n
ok.. i know the normal force is acting upwards, and weight is acting downwards, and there is also the force of the hand pushing on the pie.. but they don't give me a mass fro the pie.. so wouldn't that mean the normal froce and the wight cancel each other..
Homework Statement
The coefficient of static friction between your hand and a pie is 0.70. if you want to put a cream pie pie in someone's face, what is the minimum acceleration needed to keep it from sliding down your vertical hand? The Attempt at a Solution
Im not sure how to go about this...
