A small particle of mass `m = 2 kg` moving with constant horizontal velocity `u = 10 m//s` strikes a wedge shaped block of mass `M = 4 kg` placed on smooth horizontal surface on its inclined surface as shown in figure. After collision particle starts moving up the inclined plane. Calculate the velocity of wedge immediately after collision.

approx 5.0m/s

approx10 m/s
