A particle A of mass m initially at rest slides down a height of 1.25 m on a frictionless ramp, collides with and sticks to an identical particle B of mass m at rest as shown in the figure. Then particles A and B together collide elastically with particle C of mass 2 m at rest. The speed of particle A after the collision with particle B would be : (g = 10 m/s2)
- 2.0 m/s
- 1.25 m/s
- 2.5 m/s
- 5 m/s
Answer
(C) 2.5 m/s
