Question

Two bodies (4 kg at 3 m/s and 6 kg at 2 m/s in opposite directions) collide and stick. Velocity after collision:
  1. A
    0 m/s
    Correct
  2. B
    0.5 m/s (dir of 4 kg)
  3. C
    0.5 m/s (dir of 6 kg)
  4. D
    1 m/s

Correct answer

0 m/s

Explanation

Taking 4 kg direction positive: p = 4×3 − 6×2 = 12 − 12 = 0. v = 0/(10) = 0 m/s.
