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
Answers
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
