Diketahui:
F = 100 N
μ = 0,5
Cos 30 = 0,8
g = 10 m/s²
m1 = 10 kg --- N1 = 100 N
m2 = 8 kg --- N2 = 80 N
Ditanya: a
Jawab:
∑F = ma
F.CosΘ - f1 - f2 - T + T= (m total)a
F.Cos30 - μ.N1 - μ.N2 = (m1 + m2)a
100.0,8 - 0,5.100 - 0,5.80 = (10+8)a
80 - 50 - 40 = 18a
-10 = 18a
a = -0,5 m/s² (negatif berarti diperlambat)
Maaf kalau salah.
