Answer 1

Answer:

Explanation:

As A is sliding on the block B with an acceleration of 2 m/ s², there is relative motion between the blocks so the block a is under the action of a maximum frictional force which is providing it the acceleration of 2 m/s^². so the frictional force on A is F = 5 x 2 = 10 N

Now, this is also the frictional force acting on the 10 kg block in the backward direction. (Action-Reaction pair)

Answer 2

Explanation:

in acceleration

Force=m×a

5×2=10
