A body starts with a velocity of and accelerates uniformly at . What is its velocity after (in m/s)?

Answer and explanation

Correct answer: C. 11

  1. Step 1: Under uniform linear acceleration, velocity at elapsed time is governed by the kinematic relation .
  2. Step 2: Substitute initial speed , acceleration , and duration : .
  3. Step 3: Evaluating the arithmetic yields .
Answer
11.
Why not the others: 10 computes ; 3 computes ; 15 computes .
