Two blocks of mass 10 kg and 4 kg are connected by a spring of negligible mass and placed on a frictionless horizontal surface. An impulse gives a velocity of 14 m/s to the heavier block in the direction of the lighter block. The velocity of the centre of mass is :
- 30 m/s
- 20 m/s
- 10 m/s
- 5 m/s
Answer
(C) 10 m/s
