no 1,2,3 kak pliss besok dikumpulin... gambarnya di atas kak

1.
dik f = 50+4 N. m= 2kg
dit = a
jawab :
a = f/m
a = (50N + 4N) / 2kg
a = 54N / 2kg
a= 27 N/kg
a= 27 Kg m / s² per kg
a = 27 m/s²


2.
dik :
w= 200N
l = 2,5m = 250cm
lb = 0.5m = 50cm
lk = 250cm - 50cm = 200cm
dit : F dan KM
jawab :
f/w = lb/lk
f/200N = 50cm/200cm
f. 200 = 200N x 50
200F = 10000N
F=10000N/200
F = 50 N

KM = lk/lb
km=200cm/50cm
km=4
