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, sharp impulse of 50 Ns is given to the block with a hammer along the spring.
Calculate if the amplitude of SHM is (5/) m.
The maximum velocity is always at equilibrium position since at any other point there will be a restoring force attempting to slow the mass.
