1. Jawaban abirashiida
3. a. KM=2
b. KM = W/F, maka F= W/KM = 100N/2 =10N
4. diket; Wbeban= 3000N; s= 4m; h= 1m
dit; a. F=?
b. KM=?
c. W usaha=?
jawab;
a. s/h = W/F
maka; F = h/s . W
= 1/4. 3000
= 750N
b. KM = s/h =4/1 = 4
c. Usaha = F.s
= 750. 4 = 3000joule
5. a. usaha= W.s = 4000N. 8m = 32000joule
b. KM = s/h = 8/2 = 4
c. F= W/KM = 4000N/4 = 1000N
