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

Answer and explanation

Correct answer: B. 17

**
  1. Step 1: According to Newton's kinematics for constant acceleration, .
  2. Step 2: Plug in , , and : .
  3. Step 3: Computing the result yields .
Answer
17.
Why not the others: '5' adds acceleration directly to velocity () without multiplying by time ; '14' calculates only the velocity increase , omitting the initial velocity ; '35' multiplies instead of adding initial velocity to .
