In this diagram for acceleration for A is the equation wrong ? For B is correct i know i have a doubt about A

**Sharad**#13

Yes the equation for acceleration of block A is wrong.

The correct equation is-

mgcos37 + masin37 -T = ma'

**abhijit_2020**#14

But then according to that i am getting a' independent of g and is only dependent of a which cannot happen i am getting a'=6/5a please do it for me

Can anyone tell me by what elimination does this expression of acceleration came by equation 3,4 and 5 ?

@Tanmay_1 Sir many students prefer cengage but even I face similar problems (The solutions given are not satisfactory)

They are not giving conceptual clarity!(My opinion)

Can you suggest me some good physics resources from where I could understand concepts in good level in physics.?
