A 5 kg object is moving at 3 m/s to the right. It experiences an action-reaction force pair with a 2 kg object, resulting in the 2 kg object moving at 5 m/s to the left. What is the final velocity of the 5 kg object?
where \(m_1 = 5\) kg, \(v_{1i} = 3\) m/s, \(m_2 = 2\) kg, and \(v_{2f} = -5\) m/s. A 5 kg object is moving at 3 m/s to the right
v 1 f = 5 m/s
Let’s use the law of momentum conservation: \(v_{1i} = 3\) m/s
v f = 0.4 m/s
