Jabba has a mass of 200 kg and is zooming along in a 100 kg amusement park bumper car at 10m/s. He intentionally crashes into little Leia’s car which is sitting still. Little Leia has a mass of 25 kg and is also in a 100 kg car. After the collision, Jabba’s car is moving forward at 4.12m/s, how fast will Leia’s car be moving after the collision?

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

[tex]\rm m_1u_1 + m_2u_2+m_3u_3= v(m_1 + m_2)\\\\ 200 \times 0 + 100 \times 10 +25 \times 0= 25 \times V+ 200 \times 4.12 \\\\\ 1000=25V+824\\\\ 25V= 1000-824 \\\\ V=7.04 \ m/sec[/tex]

Hence, the velocity of the Leia’s car to be moving after the collision will be 7.04 m/sec
