Expert Solution
Step 1

Given Information:-

Mass of the block A is mA=5 kg

Mass of the block B is mB=50 kg

Coefficient of kinetic friction is μk=0.2

 

Required:-

We need to calculate acceleration of the system and tension in the cord.

Free-body diagram:-

Physics homework question answer, step 1, image 1

 

In the free-body diagram 

T is the tension in the cord, a is the acceleration of the system, f is the frictional force on A, g is the gravitational acceleration and N is the normal reaction force on A by the table.
