A car with an initial speed of accelerates at for . How far does it travel (in m)?

Answer and explanation

Correct answer: D. 22

**
  1. Step 1: The distance covered under constant acceleration is .
  2. Step 2: With , , and , write .
  3. Step 3: Summing the contributions gives .
Answer
22.
Why not the others: '14' calculates only the distance at initial velocity (), omitting the acceleration displacement; '24' is an arithmetic error in applying ; '30' omits the factor of on the acceleration term, calculating .
