Verified answer
Ftotal = 35-10-5 = 20 NF = m. a
20 = m . 4
m = 5
F = m. a
20 = 10 . a
a = 2 m/s
Sub bab : Hukum Newton
Diketahui :
F1 = -10 N
F2 = -5 N
F3 = +35 N
a1 = 4m/s²
m2 = m+5 kg
Ditanya :
a2 = ?
Penyelesaian :
*Cari Ftotal
Ftot = F1+F2+F3
Ftot = -10 N-5N+35N
Ftot = 20 N
Kondisi 1
*Cari massa M
Ftot = M. a
20 = M. 4
M = 5 kg
Kondisi 2
*Cari percepatan
Ftot = Mtot. a
20 = (5+5) a
20 = 10a
a = 2 m/s²
Jadi, besarnya percepatan benda setelah ditambahkan beban 5 kg adalah 2 m/s²
Jawaban : A
semoga membantu
