dua buah bola masing-masing mempunyai massa 60 kg berada diatas sebuah perahu yang bermassa 140 kg bila perahu bergerak dengan kecepatan 10 meter per sekon maka momentum yang dimiliki oleh sistem adalah

Jawaban : 2000 kgm/s

Diketahui:
m = 60 kg + 140 kg = 200 kg
v = 10 m/s

Ditanya: p = … ?

Pembahasan:

Momentum didefinisikan sebagai hasil perkalian antara massa dan kecepatan benda. Secara matematis dirumuskan sebagai berikut.

p = m · v

Keterangan:
p : momentum (kgm/s)
m : massa benda (kg)
v : kecepatan benda (m/s)

Dengan menerapkan rumus di atas, diperoleh:

p = m · v
p = 200 · 10
p = 2000 kgm/s

Jadi, momentum yang dimiliki oleh sistem tersebut adalah 2000 kgm/s.

Babies get sick more often than older children or adults because their immune systems are not fully developed and functioning at full capacity , The common cold , which is an infection of the respiratory system caused by a virus , is the most frequent malady . Doctors say that normal , healthy babies get up to about seven colds before they reach their first birthday . Another common affliction is the flu , caused by a different family of viruses , which bring on high fever , chills , fatigue , and sometimes digestive symptoms like vomiting and diarrhea , in addition to the respiratory symptoms of a cold . Another reason babies get sick so often is that they are frequently around other children , often siblings , and this exposes them to viruses and bacteria at school and daycare . Children at schools and daycare get more colds , runny noses , and earinfections than children cared for at home . However , their earlier exposure to these diseases also leads them to develop immunity earlier
