Answer 1

Verified answer

4. w bulan = m. g bulan
w bulan = 100kg . 1,6 m/s^2
w bulan 160 N

5. a = ΣF/m
a = m.g.sinθ/m
a = 4.10 sin 30°/4
a = 10 . 1/2
a = 5 m/s^2

Answer 2

Verified answer

4. Diket : m = 100 kg
               g = 1,6 m/s^2
Ditanya : W = ?
Jawab : W = m.g
                  = 100.1,6
                  = 160 N (opsi a)

5. Diket : m = 4 kg
               θ = 30°
               g = 10 m/s^2
Ditanya : a = ?
Jawab : a = g.sinθ
                = 10.sin30°
                = 10.1/2
                = 5 m/s^2 (opsi b)
