Basic friction problems

  1. Sep 27, 2012 #1
    Hi guys,

    I have a test in 3 hours so in trying to understand static and kinetic problems utilizing mew. Here's my problem:

    A block of mass 3.00 kg is pushed up against a walk by a force P that makes the angle of theta = 30.0 angle with the horizontal. The coefficient of static friction between the block and wall is 0.25. (A) determine the possible values for he magnitude of P that allow the block to remain stationary. (B) what happens if |vector P| has a larger value than |P_max|? What happens if |vector P| has a smaller value than |P_min|?

    Sorry for any difficulty in understanding symbols. I'm in calculus and typing this out on my phone.
