Question
Two springs with negligible masses and force constant of 
are attached to the block of mass m = 10 kg as shown in the figure. Initially the block is at rest, at the equilibrium position in which both springs are neither stretched nor compressed. At time t = 0, a sharp impulse of 50 Ns is given to the block with a hammer.
- Period of oscillations for the mass m is
- Maximum velocity of the mass m during its oscillation is 5 ms–1.
- Data are insufficient to determine maximum velocity
- Amplitude of oscillation is 0.42 m
The correct answer is: Period of oscillations for the mass m is
