Question

question 6 of 28. which of the following best expresses the law of conservation of momentum for an inelastic collision between two objects? a. (m1 + m2)vf = m1vi1 + m2vi2 b. m1vi1 + m2vi2 = (m1 + m2)vf c. m1vf + m2vf = m1vi1 + m2vi2 d. m1vf + m2vf = m1vi1 + m2vi2

Explanation:

The law of conservation of momentum states total initial momentum equals total final momentum. For inelastic collisions, objects may stick, so final momentum is combined mass times common velocity.

Answer:

B. \( m_1 \vec{v}_1 + m_2 \vec{v}_2 = (m_1 + m_2) \vec{v}' \)
