A 2 kg blob of putty moving at 3 m/s slams into a 3 kg blob of putty at rest. Which blob has the most momentum prior to the collision?

Respuesta :

initial momentum of 2 kg blob is given as

[tex]P_1 = m_1v_1[/tex]

here we have

[tex]m_1 = 2kg[/tex]

[tex]v_1 = 3m/s[/tex]

[tex]P_1 = 3(2) = 6 kg m/s[/tex]

initial momentum of 3 kg blob is given as

[tex]P_2 = m_2v_2[/tex]

here we have

[tex]m_2 = 3kg[/tex]

[tex]v_2 = 0m/s[/tex]

[tex]P_2 = 3(0) = 0 kg m/s[/tex]

So initially 2 kg Blob has most momentum before they collide
