A force of \(5\ N\) gives a mass \(m_1\), an acceleration of \(10\ m\ s^{–2}\) and a mass \(m_2\), an acceleration of \(20\ m\ s^{-2}\). What acceleration would it give if both the masses were tied together?
  
From the Newton's second law, We know that,
 
Mass of the first object (\(m_1\)) \(=\)  \(kg\)
 
Mass of the second object (\(m_2\)) \(=\)  \(kg\)
 
Acceleration produced in the combined mass \(=\)  \(m\ s^{-2}\)
