Find the mass Mf of the hanging block in figure 5 E16 which will prevent the smaller block from slipping over the triangular block All the surfaces are frictionless and the strings and the pulleys are light 8 34 Find the acceleration of the blocks A and B in the three situations shown in figure 5 E17 A 4 kg 5 kg A B A 4 M 2 ko Figure 5 E16 A 29 Figure 5 E17 13 Joga 305 kg 1 b 3 100 g 50 g 30 Figure 5 E18 1 kg 500 g 291 3 35 Find the acceleration of the 500 g block in figure 5 E18 P A 09 c 2 kg K 36 A monkey of mass 15 kg is climbing on a rope with one end fixed to the ceiling If it wishes to go up with an acceleration of 1 m s how much force should it apply to the rope If the rope is 5 m long and the monkey starts from rest how much time will it take to reach the ceiling 165 TOS A monkey is climbing on a rope that goes over a smooth light pulley and supports a block of equal mass at the other end figure 5 E19 Show that whatever force the monkey exerts on the rope the monkey and the block Slo move initially both were change as time passes Figure 5 E19 The monkey B shown in figure 5 E20 is holding the tail of the monkey A which is climbing up The masses of the monkeys A and B are 5 kg a respectively If A can tolerate a tension of 30 tail what force should it apply on the rope in carry the monkey B with it Take g 10 m s 70N 100N Figure 5 E20 1 c 7 d 13 a 2 8 14 1 b d 4 a c 7 c d 1 10 N 39 Figure 5 E21 shows a man of mass 60 kg stand 2 3 1 10 a light weighing machine kept in a box of mass The box is hanging from a pulley fixed to the a 3 1 1 10 through a light rope the other end of which is h 4 5 N and the man himself If the man manages to keep th at rest what is the weight shown by the machine force should he exert on the rope to get his correct 6 0 25 Na 5 F 2 on the machine the mo m 7 F 1 777
