Jawaban:
Kalo ditanya momentumnya: a. 2000 kgm/s e barat
Penjelasan:
m a = 1000 kg
v a = 10 m/s
m b = 1500 kg
v b = -8 m/s (minus karena ke arah kiri)
Momentum mobil a
p a = m x v
p a = 1000 x 10
p a = 10.000 kgm/s
momentum mobil b
p b = m x v
p b = 1500 x (-8)
p b = -12.000 kgm/s
jumlah momentum
p a + p b = 10.000 - 12.000 = -2.000 kgm/s (krn - jadi arahnya ke kiri/barat)
