Question

15. A ball 'A' of mass 100 gm moving at 2m/s collides with another identical ball 'B' moving at 3m/s
along the same line. There is no loss in energy during collision. Then, the speed of the balls 'A' and
'B' after the collision are?
(A) 1 m/s and 4 m/s
(B) 2 m/s and 3 m/s
(C) 3 m/s and 2 m/s
(D) 2.5 m/s and 2.5 m/s​

Answer 1

Answer:

d is correct answer

Step-by-step explanation:
