PhysicsEasysingle choice

The pulley system, shown in the figure, has two pulleys of radii $2 m$ and $1 m$ , respectively. If the acceleration of block $A$ is $5 m s^{- 2}$ in the downward direction, then the acceleration of block $B$ will be

Options:

Answer:

Solution:

Given $a_{A} = α \times 2 m = 5 m s^{- 2}$

$\Rightarrow α = \frac{5}{2} m s^{- 2}$

Hence, acceleration of $B$ , $a_{B} = α \times 1 m = \frac{5}{2} m s^{- 2}$
