Newton's Laws of Motion problem 10


Two bodies with masses and lying on a horizontal smooth surface are connected by a light rope. The rope breaks at a force greater than . Two forces and begin to act on the bodies in opposite directions as shown in the figure below. The constant , and is the time in seconds.


Body on a horizontal smooth surface .



  • Obtain an equation that shows the change in the acceleration of the bodies with time.

  • What is the force in the rope after from the start of the forces?

  • How long does it take for the rope to break?
