tolong dijwb y kk pliss. tuk dikumpulin sekarang

Itu menggunakan rumus :
W = m × g

1) W = mg
50 N = m × 10m/s^2
m = 50 N : 10m/s^2
m = 5 kg

2) W = mg
W = 4kg × 9,8m/s^2
W = 39,2 kg.m/s^2 = 39,2 N

3) W = mg
65 N = m × 9,8m/s^2
m = 65N : 9,8m/s^2
m = 6,63 kg

4) W = mg
48N = 51 kg × g
g = 48/51 = 0,94m/s^2

5) W = mg
196N = m × 9,8m/s^2
m = 196N : 9,8m/s^2
m = 20kg

dikoreksi lagi ya.. semoga membantu ^^
