Hi, I need help with the following problem:
You are pushing a mop of mass m with a force P at an angle theta. The coefficiant of friction is [tex]U_k [/tex].
Find P so that the mop will start moving in terms in [tex]\theta,U_k ,m,g [/tex].
I solved this part and got:
[tex]
P = \frac {(U_k *mg )}{( \sin\theta- U_k*\cos\theta)} [/tex]
Now, for part 2 I have to find the minimum angle [tex] \theta [/tex] for which it will be impossible for me to push the mop in terms of [tex]\theta,U_k ,m,g,P [/tex]..
Like at 90 degrees It is impossible to push the mop. Any help on part 2 would be appreciated.
Thanks
