23. (II) Arlene is to walk across a \"high wire\" strung horizontally between two buildings 10.0 m apart. The sag in the rope when she is at the midpoint is 100", as shown in Fig. 447. If her mass is 50.0 kg, what is the tension in the rope at this point? FIGURE 4-47 Problem 23. FIGURE 4-53 Problems 32 and 33. Mass m A rests on a smooth horizontal surface; m3 hangs vertically. 33. (II) (a) If mm = 13.0 kg and m3 = 5.0 kg in Fig. 453, determine the acceleration of each block. (b) If initially m A is at rest 1.250 m from the edge of the table, how long does it take to reach the edge of the table if the system is allowed to move freely? (c) If m3 = 1.0 kg, how large must m A be if the acceleration of the system is to be kept 1 at mg? 13. (II) A 75-kg petty thief wants to escape from a third-story jail window. Unfortunately, a makeshift rope made of sheets tied together can support a mass of only 58 kg. How might the thief use this \"rope\" to escape? Give a quantitative answer. 15. (ll) Can cars \"stop on a dime\"? Calculate the acceleration ofa 1400-kg car if it can stop from 35 km/h on a dime (diameter = 1.7 cm). How many g's is this? What is the force felt by the 68-kg occupant of the car
