1. Berat
W=m.g = kg . ms2 = M
LT2 = [ MLT -2 ]
Usaha
W= F.s ------> m.a ------> kg. ms2 . m
------> kgm2
m2 = M. L
2
T 2 = [ M L T-2]
Gaya
F= m.a = kg. ms2 = M . LT 2 = [ MLT-2]
2.

Va = 15 arahnya (VW)°
Vb = 20 arahnya (XY)°
45 ° ket : VW =11
11° XY=45
(0,0) ∅=45°−11°=34 ° X
R = √a2+b2+2.a .b .cos∅
= √152+202+2.15 .20.cos34 = √225+400+2.15.20 .0,83
= √625+30.16,6
= √625+498
= √1123
= 33,5 m
V=dt = 33,510 = 3,35 m/s
