m1 = 5 kg, m2 = 10 kg
g = 10 m/s²
F1 = 20 N, F2 = 30 N
a = __?
T = __?
f1 = μ m1 g = 0,1 • 5 • 10 = 5 N
f2 = μ m2 g = 0,1 • 19• 10 = 10 N
tinjau sistem keseluruhan
ΣF = Σm a
F1 + F2 - f2 - f1 = (m1 + m2) a
20 + 30 - 10 - 5 = (5 + 10) a
35 = 15 a
a = 7/3 m/s² ← jwb
tinjau benda m1
ΣF = m a
T - f1 = m1 a
T - 5 = 5 • (7/3)
T = 5 + 35/3
T = 22/3 N ← jwb
