In given figure A & B are connected by ideal pulley, find acceleration of A (in $m / s^{2}$ ). (All surfaces are smooth).

pulley system

Answer:

Solution:

For A (40 kg): $40 g - T = 40 a$ ...(i)

String constraint makes B's acceleration $4 a$ ; for B (10 kg): $\frac{T}{4} = 10 \times 4 a$ ...(ii)

Solving (i) and (ii): $a = 2 m/ s^{2}$ .
