A person (mass m1) who is kneeling on a plywood panel (mass m2) wishes to push himself and the panel away from the right-hand wall. Determine a condition on µ,2 which would allow him to do this, as opposed to his slipping relative to a stationary panel. The two applicable coefficients of static friction are µ,1 and µ,2. Evaluate µ,2 for m1 = 80 kg, m2 = 10 kg, and µ,1 = 0.60.
