Find the acceleration of body of mass 2kg from the figures shown. (Ans: 5m/s²,2m/s²)
Answers
Image Attached is not Clear. It is blurred. Thus, the Force on the Pulley is not clear.
Let us assume the Force as per as the Answer.
In First case, Let the Force be 10 N.
Given, Mass of the body (or Pulley) = 2 kg.
Using Newton's second law of motion,
Force = mass × acceleration.
∴ Acceleration = 10/2
⇒ a = 5 m/s².
In second Pulley,
Let the Force be 4 N.
∴ acceleration = 4/2
⇒ a = 2 m/s².
Note ⇒ The Assumption of the force is done because the image is not clear and the assumption is done as per as the answer given. We simply cannot assume that.
In the question there must be the Force given. By substituting the force given you can get the answers. But Remember that the method is right.
Hope it helps.
