25 = 5 v 1 f
where \(m_1 = 2\) kg, \(v_{1i} = 4\) m/s, \(m_2 = 3\) kg, and \(v_{2i} = -2\) m/s. 25 = 5 v 1 f where
Let’s use the law of momentum conservation: \(v_{1i} = 4\) m/s
Momentum is the product of an object’s mass and velocity. The law of momentum conservation states that the total momentum of a closed system remains constant over time, unless acted upon by an external force. \(m_2 = 3\) kg
This law is useful in solving problems related to collisions and explosions, where the momentum of the objects involved changes.
