= 245/25
= 9,8 m/s
2. m = F/a
= 20/2
= 10 kg
3. W = F.s
= 400.4
= 1600 N
m = 25 kg
F = 245 N
tent. = a
rumus : F = a × m
a = F ÷ m
a = 245 ÷ 25
a = 9,8 m/s
2. dik :
F = 20 N
a = 2 m/s
tent. = m
rumus : F = a×m
m = F÷a
m = 20 ÷2
m= 10 kg
3. dik
F = 400
s = 4m
tent. w = ....?
rumus : w = F × s
w = 400 ×4
w = 1600
