The velocity of a particle is m/s. Find its displacement from to .

Answer and explanation

Correct answer: B. -8 m

  1. Step 1: Integrate to find displacement: . Step 2. At : m, and at . Answer: -8 m. Why not the others: 8 m: The sign is reversed; the displacement is the integral of the velocity. 0 m: That is the velocity at , not the displacement. 16 m: That integrates only the first term.
