# Dual Springs

A block of mass $$M=3\text{ kg}$$ is initially in equilibrium and hanging by 2 identical springs as shown in figure above. If one of the springs is cut from the lower point at $$t=0$$, then find acceleration of block in $$\text{m/s}^2$$ at $$t=0$$.

Details and Assumptions:

• Do not consider rotational effects of the block.

• Take $$g=-10\text{ m/s}^2$$.

• Take upward as positive direction
