Question

In the pulley system shown, if the radii of the bigger and smaller pulleys are $2 m$ and $1 m$ respectively and the acceleration of block $A$ is $5 m / s^{2}$ in the downward direction, then the acceleration of block $B$ will be:

Open in App

Solution

Given,
$a_{A} = 2 a = 5 m / s^{2}$
$a = \frac{5}{2} r a d / s^{2}$
$a_{B} = 1. (a) = \frac{5}{2} m / s^{2}$
Final Answer: $(d)$
