Question

In the setup shown, find acceleration of the
block C.
2 m/s2
1 m/s21 B ?
C
(B) 3 m/s2
(D) 5 m/s2
(A) 3 m/s2 1
(C) 5 m/s21​

Answer 1

The acceleration of block C is in downward direction i.e. 3 m/s^2

Option (A) is correct.

Explanation:

Acceleration of the block B with respect to the pulley in the upward direction = Acceleration of the block C with respect to the pulley in the downward direction

AB, P(y) = AC,P (−y)

AB (y) − AP (y) = AC (−y) − AP (−y)

1 - 2 = Ac (-y) - (-2)

- 1 = Ac(-y) + 2

Ac (-y) = - 3 m/s^2

Acceleration of block C is in downward direction = - 3 m/s^2

Therefore in downward direction it will be positive i.e. 3 m/s^2

Answer 2

Answer:

m/sec²
