10 Eigure 5.9 shows three blocks being pushed across a frictionless floor by horizontal force F. What total mass is :+ + :> accelerated to the right by [a] force F, [b] force F21 on block 2 from block 1, and [c] force Egg on block 3 from block > > > 2? [d] Rank the blocks according to their acceleration magnitudes, greatest first. [e] Rank forces F, F21, and F32 according to magnitude, greatest first. Ikg gure 5.9 Question 10. 26 E The tension at which a fishing line snaps is commonly called the line's "strength." What minimum strength is needed for a line that is to stop a salmon of weight 85 N in 11 cm if the fish is initially drifting at 2.8 m/s? Assume a constant deceleration.50 III @ In g. 5.29. three ballot boxes are connected by cords, one of which wraps over a pulley having negligible friction on its axle and negligible mass. The three masses are mg = 30.0 kg. m3 = 40.0 kg. and mg = 10.0 kg. When the assembly is released from rest, [a] what is the tension in the cord connecting B and C, and [b] how far does A move in the first 0.250 s [assuming it does not reach the pulley]?

(a) Figure 6.29a is a plot of the required magnitude F of the net centripetal force for a range of possible values of the passenger's speed v. What is the plot's slope at v = 8.30 m/s? (b) Figure 6.29b is a plot of F for a range of possible values of 7, the period of the motion. What is the plot's slope at 7 = 2.50 s? F F T (a) (b)
