Question

A block of mass Mis pulled along a smooth horizontal surface with a rope of mass m. If the force applied
at the free end of the rope is F, the acceleration of the block will be​

Answer 1

Answer:

Consider the system as a whole

A block of mass M and a rope tied to it of mass m pulled by a force P,

The only external force

The system will accelerate due to the action of the force , all accelerating with same acceleration

Acceleration of the system = Total external force/Total mass

a = P/m+ M

Therefore acceleration of the block of mass M will also be a

Net force on it  = mass x acceleration  

This force is force of the rope on the block

Hence F = PM/m+ M
