Problem 6-1 The coefficient of static friction between Teflon and scrambled eggs is about 0.04. What is the smallest angle from the horizontal that will cause the eggs to slide across the bottom of a Teflon-coated skillet? θ θ = 2.3 o

Problem 6-7 A 3.5 kg block is pushed along a horizontal floor by a force F of magnitude 15 N at an angle θ = 40° with the horizontal (Figure 6-20). The coefficient of kinetic friction between the block and the floor is 0.25. Calculate the magnitudes of (a) the frictional force on the block from the floor and (b) the block's acceleration . θ F F cos θ F sin θ F g = mg F f = µ k N N F f = 11 N a = .14 m/s 2
A 4.10 kg block is pushed along a floor by a constant applied force that is horizontal and has a magnitude of 40.0 N. Figure 6-26 gives the block's speed v versus time t as the block moves along an x axis on the floor. What is the coefficient of kinetic friction between the block and the floor? F
