Question

A massless rope passes over a massless pulley suspended from the ceiling. A 4kg block is attached to one end and 5kg block attached to other end. The acceleration of the 5kg block is
A) g/4
B) 5g/9
C) 4g/9
D) g/9

Answer 1

Answer:

D) g/9

Explanation:

we know,

$a = (m \frac{}{1} - m \frac{}{2} ) g \div (m \frac{}{1} + m \frac{}{2} ) \\ for \: m \frac{}{1} > m \frac{}{2}$

so, here m1 is 5kg and m2 is 4kg.

thus, a = g/9

$a = g \times (1 \div 9)$
