6. Newton's Laws Of Motion question bank (Physics)

A block of mass \(M\) is pulled along a horizontal frictionless surface by a rope of mass \(m\). If a force \(P\) is applied at the free end of the rope, the force exerted by the rope on the block is

A certain force gives an object of mass \(m_1\) an acceleration of \(12 \, \text{m/s}^2\) and an object of mass \(m_2\) an acceleration of \(3 \, \text{m/s}^2\). What acceleration would the force give to an object of mass \(m_2 - m_1\)?
