mbenda = 10 kg
mkatrol = 2 kg
F = 122 N
Ditanya :
a ?
Penyelesaian :
Benda :
Ftotal = ma
T - wb = (mbenda + mkatrol) a
T - (mbenda + mkatrol) g = ( 10 + 2 ) a
T - (12)(10) = 12a
T - 120 = 12a
Gaya :
Ftotal = ma
F - T = mbenda a
122 - T = 10a
Percepatan :
T - 120 = 12a
-T + 122 = 10a +
2 = 2a
a = 2 / 2
= 1 m/s2 ( A )
