Question

find the acceleration of block b ​

Answer 1

Answer:

There will no any acceleration.

Answer 2

Answer:

Explanation:

let acceleration of 8kg block is a

then acceleration of 5kg block will be 2a

applying equation for 5 kg block

8g-t = 8a

t/2 - 5g = 10a

t-10g = 20a

adding 1 and 3

-2g = 28a

-g/14 = a

that means 8kg moves upward by g/14 acceleration

and 5kg moves downward by g/7 acceleration
