Question

A 1 kg mass is on a rough horizontal surface is joined with a 2 kg mass by a light , inextensible string running over a frictionless pulley.
Will 1 kg mass moves at zero, higher or lower acceleration . Explain based on Newton's law and state the law?

Answer 1

Answer:

The one kg mass will move with acceleration given by (net force/mass of 1kg)=(20-10)/1=10m2/s2

Both masses will move at same acceleration as they are connected by string
