Bantu jawab dung saya kurang ngerti
Jawaban:
percepatan ( a ) = 10 m/s²
tegangan ( T ) = 30 N
Penjelasan:
dik :
m1 = 3 kg
m2 = 2 kg
g = 10 m/s²
dit :
a & T
jawab :
Sigma F = m.a
a = Sigma F / m
a = (m1+m2) . g / m1+m2
a = ( 3+2) . 10 / 3+2
a = 5.10 / 5
= 50/5 = 10 m/s²
tegangan tali :
Cara 1
T = m1.a
3.10
= 30 N
Cara 2
Sigma F = m2.a
F - T = m2.a
50 - T = 2.10
50 - 2.10 = T
50 - 20 = T
30 N
semoga bermanfaat jadikan jawaban terbaik yaaa
