W = 40 N
W = m x g
m = W/g
m = 40/10 = 4 Kg
P = m x v
= 4 x 35
= 140 Kg m/s (Jawaban D
23.)
I = F x t
I = 300 x 0,3
I = 90 Ns (Jawaban B)
24.)
mAvA + mBvB
C = _____________
mA + mB
3 (2) + 2(-3)
C = ___________
3 + 2
C = (6 - 6)/5
C = 0 m/s
vA' = C + e (C - vA)
vA' = 0 + 1 (C - 2)
vA' = 0 - 2
vA' = -2 m/s (berlawana arah dengan gerak semula)
Jadi, kecepatan bola A setelah tumbukan adalah 2 m/s (Jawaban A)
