is attac led to one end of a mass less spring of force constant K lying on a frictionless horizontal plane The particle starts moving horizontally from its equilibrium position at time t 0 with an initial velocity up When the speed of particle is 0 5u it collides elastically with a rigid wall After this collision Vmax Uo A 1 the instant of time at which the particle passes through the equilibrium position for 1st time is t 2 m 3 VK 2 the instant of time at which the particle passes through the equilibrium position for 1st time is T m 3 VK t 3 the instant of time at which the particle passes through the equilibrium position for 1st time is m 6 VK t 4 the instant of time at which the particle passes through the equilibrium position for 1st time is
