in the pulley block diagram shown in figure. The relation between acceleration of blocks A and B

Answer 1

Answer:If you move the end of the rope 6 m, you take 6 m “out of the system". If there are three ropes coming from the moving block, each contributes 2 m and the block moves 2 m. The block starts to move when the rope is pulled and stops moving when the rope stops moving. So speed of the block is 1/3 of the speed of the end of of the rope. Acceleration is also 1/3 by the same arguement.So block distance, speed and acceleration = rope distance, speed and acceleration divided by the number of ropes from the moving block.Explanation:In the pulley-block arrangement., find the relation between acceleration of blocks A and B.Solution-ᴀ = 3 , ʙ =
