Chapter , Problem 32(choose chapter or problem)
A block is pushed across a floor by a constant force that is applied at downward angle (J (Fig. 6-19). Figure 6-36 gives the acceleration magnitude Q versus a range of values for the coefficient of kinetic friction JLk between block and floor: Q) = 3.0 mls2, JLk2 = 0.20, and JLk3 = 0.40. What is the value of ()?
