Question

In the figure shown assume ideal string and pulley, the acceleration of the blocks A and B are:-​

Answer 1

Answer:

Explanation:

let acceleration of a = a downwards

therefore acceleration of  b will be a/2 upwards

now apply equations of motion

mg-t =ma

2t-mg = ma/2

2mg-2t = 2ma

mg=5ma/2

a=2g/5 = 4m/s^2

therefore acceleration of a  =4m/s^2 upwards

and acceleration of b = 2 m/s^2 downwards
