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

Answer and explanation

Correct answer: B. 56

**
  1. Step 1: The distance covered under constant acceleration is .
  2. Step 2: With , , and , write .
  3. Step 3: Summing the contributions gives .
Answer
56.
Why not the others: '8' calculates only the distance at initial velocity (), omitting the acceleration displacement; '104' omits the factor of on the acceleration term, calculating ; '60' is an arithmetic error in applying .
