(tentukan percepatan dan tegangan tali) bantu dong ???

DINAMIKA
• gaya

bidang datar licin
m₁ = 3 kg
m₂ = 5 kg
F = 40 N
a = __?
T = __?

tinjau sistem keseluruhan
F = Σm a
F = (m₁ + m₂) a
40 = (3+5) a
40 = 8 a
a = 5 m/s² ✓

tinjau benda m₁
T = m₁ a
T = 3 • 5
T = 15 N ✓

cek
Tinjau benda m₂
F - T = m₂ a
40 - T = 5 • 5
40 - T = 25
T = 15 N
