Question

Two bodies of equal mass(m) moving with
equal speed (v) in opposite directions collide. The
resultant velocity of the combination is
Ha) zero (b) 2v (c) v (d) - V ​

Answer 1

Answer:

0

Explanation:

using momentum conservation law

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

mu + m(-u) = (m+m)v

0 = 2mv

v=0

Answer 2

Answer:

Explanation:

using momentum conservation law

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

mu + m(-u) = (m+m)v

0 = 2mv

v=0
