A person (mass m1) who is kneeling on a rough wood panel (mass m2) wishes to push himself and the panel away from the right-hand wall (Figure 1). The two applicable coefficients of static friction are and . 1.1 Discuss, how the person can push himself and the panel away from the right-hand wall without calculations. 1.2 Draw free body diagrams for the person and panel indication all the forces. 1.3 Determine a condition on in terms of u, m1 and m2, which would allow him to do this, as opposed to his slipping relative to a stationary panel. 1.4 Evaluate for m1 = 65 kg, m2 = 15 kg, and = 0.42. Marks] 1.5 According to the developed mathematical model, state whether the person able to push himself opposed to the friction force or not. Marks]
