A small, 150 g cart is moving at 1.60 m/s on a frictionless track when it collides with a larger, 5.00 kg cart at rest. After th
NemiM [27]

Answer:

Mass of larger cart will be 0.0213 m /sec

Explanation:

We have given mass of small cart m_1=150gram=0.150kg

Initial velocity of small cart v_{1i}=1.6m/sec

Mass of larger block m_2=5kg

Initial velocity of larger cart v_{2i}=0m/sec

After the collision velocity of smaller cart v_{1f}=-0.890m/sec

Now according conservation of momentum

m_1v_{1i}+m_2v_{2i}=m_1v{1f}+m_2v_{2f}

0.150\times 1.6+5\times 0=0.150\times -0.890+5\times v_{2f}

5\times v_{2f}=0.1065

v_{2f}=0.0213m/sec
