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. 32

**
  1. Step 1: Apply the first kinematic equation for constant acceleration: , where is initial velocity, is acceleration, and is time.
  2. Step 2: Substitute the given parameters , , and : .
  3. Step 3: Calculate the product and add: .
Answer
32.
Why not the others: '72' multiplies instead of adding initial velocity to ; '24' calculates only the velocity increase , omitting the initial velocity ; '12' adds acceleration directly to velocity () without multiplying by time .
