Marks: +1, -0

A particle of mass m is attached to one end of a massless spring of force constant k, lying on a frictionless horizontal plane. The other end of the spring is fixed. The particle starts moving horizontally from its equilibrium position at time t=0 with an initial velocity u0. When the speed of the particle is 0.5u0, it collides elastically with a rigid wall. After this collision,

the speed of the particle when it returns to its equilibrium position is u0. The time at which particle passes through equilibrium for second time is, t=‌
