Question

Collision: A 1875 - kg car going 23 m/s collides head on with a 1025 - kg compact car parked on ice. After the collision, the first car moves in the same direction at 13 m/s.

Answer 1

How fast and in what direction does the second car move after the collision?

Answer 2

We can use the conservation of momentum. \[m_1v_1 = m_1v'_1 + m_2v'_2\]
