Question

In the figure, the spring is compressed by $x_{0}$ and released, Two blocks $A$ and $B$ of masses $m$ and $2 m$ , respectively, are attached at the ends of the spring. Blocks are kept on a smooth horizontal surface and released. Find time Period of oscillation?

Solution

Time period of oscillation of system is,
$T = 2 π \sqrt{\frac{μ}{k}}$ where $μ = \frac{m_{A} m_{B}}{m_{A} + m_{B}} = \frac{m (2 m)}{m + 2 m} = \frac{2 m}{3}$
$T = 2 π \sqrt{\frac{2 m}{3 k}}$

Two identical blocks P and Q have mass ‘m’ each. They are attached to two identical springs initially unstretched. Now the left spring (along with P) is compressed by $\frac{A}{2}$ and the right spring (along with Q) is compressed by A. Both the blocks are released simultaneously. They collide perfectly inelastically. Initial time period of both the blocks was T. [consider k as spring constant of each spring]

The time period and amplitude of oscillation of the combined mass is respectively,
