Per NCERT §5.11.2 Case I, in an elastic 1D collision between EQUAL masses (one at rest), the result is which?
AFirst reverses; second stays at rest
BBoth move with v₁/2 each
CFirst mass stops; second moves with v₁
DBoth stop after collision
Answer & Solution
Correct answer: C. First mass stops; second moves with v₁
NCERT §5.11.2 Case I: m₁ = m₂ ⇒ v_{1f} = 0 and v_{2f} = v_{1i}. Velocity is transferred entirely.
