A particle of mass m moves in circle of radius r with constant speed v. Magnitude of momentum change in half revolution:

  1. πmv
  2. 2mv
  3. 0
  4. mv
Show answer and solution

Correct answer: B. 2mv

**Half revolution:** velocity reverses direction. Δp = mv_final - mv_initial = mv - (-mv) = 2mv (vectorially).
