11. 121 = (2+9)(a)
a = 11 m/s2
12. 75 = (2+3)(a)
a = 15 m/s2
13. 50 - 23 = (2+7)(a)
a = 3 m/s2
16. Fg del bloque de 6kg = 60
Fg del bloque de 4kg = 40
F.R. = 60-40 = 20
20 = (6+4)(a)
a = 2 m/s2
17. Fg del bloque de 9 kg = 90
F.R. = 90
90 = (11+9)(a)
a = 4,5 m/s2
18. Fg del bloque de 1kg = 10
F.R. = 120-10-40 = 70
70 = (1+4)(a)
a = 14 m/s2
