Question

Two blocks,each of mass 3.0 kg are connected by a light cord and placed on a horizontal surfabe when a horizontal force of 20 newton is applied on a block an accn of 0.50 metre per second square is produced find(a)tensiom(b)force of friction which is same

Answer 1

net force=mass*acceleration
20N-friction=6kg*a
20=frictionforce=3
friction force=17N

Answer 2
