Question

Two identical balls A and B having velocities of
0.5 m/s and -0.3 m/s respectively collide
elastically in one dimension. The velocities of B
and A after the collision respectively will be
[NEET (Phase-2) 2016]
(1) -0.5 m/s and 0.3 m/s
(2) (1.414)
(2) 0.5 m/s and -0.3 m/s
0.01
(3) -0.3 m/s and 0.5 m/s.
(4) 0.3 m/s and 0.5 m/s​

Answer 1

(2) 0.5 m/s and - 0.3m/s

Explanation:

in elastic collision, the velocities will interchange becàuse the masses are identical.
