Question

InFig. 6.178, find the acceleration of B, if the acceleration

of A is 2 ms.​

Answer 1

Answer:

1m/s-²

Explanation:

total length of the string is constant. if block B moves a distance y and A by x then total elongation of string = 4y

contraction of string = 2x

therefore : 2xy - 2x = 0

2y = x

take twice time derive = 2ve

2y = x

given x = 2m/s-²

y = 1m/s-²

here x = A, y = B
