In the figure, a slab of mass m1 = 40 kg rests on a frictionless floor, and a block of mass m2 = 9 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40. A horizontal force F of magnitude 108 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?

Step 1

Given that the normal reaction force is 88.2 N and the coefficient of kinetic friction is 0.4, the friction force can be calculated as: \[ F_{\text{friction}} = \mu_k \times \text{Normal reaction} = 0.4 \times 88.2 = 35.28 \, \text{N} \] Show more…
