A body of mass 2kg is placed on a horizontal frictionless surface. It is connected to one end of a spring whose N force constant is 250. The other end of the spring is m joined with the wall. A particle of mass 0.15kg moving horizontally with speed v sticks to the body after collision. If it compresses the spring by 10cm, the velocity of the particle is (a) 3 m/s -oooooooo (b) 5 m/s M (m) (c) 10 m/s (d) 15 m/s A body of mass 2kg is placed on a horizontal frictionless surface.
