Question

a force of 9 Newton Pulls block of 4 kg through a rope of mass 0.5 kg the block is resting on smooth surface what is the force of reaction exerted by the block on the rope

Answer 1

Answer:

Here is your answer.Thank you.

Answer 2

Answer:

The force of reaction exerted by the block on the rope is 8 Newton.

Explanation:

Mass of the block = 4 Kg

Force pulling the block = 9 N

Mass of the rope = .5 Kg

We know that,

Force = Mass × Acceleration

F = m × a

9 = (4+.5)×a

a = 9/(4+.5)

a = 9/4.5

a = 2 m/s²

Now,

Force of reaction = Mass of block × Acceleration of the block

                            = 4×2

                            = 8 N

So, the answer is 8 Newton.
