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

Answer and explanation

Correct answer: B. 150

**
  1. Step 1: Apply the displacement-time formula .
  2. Step 2: Plug in , , and : .
  3. Step 3: Calculating both terms yields a total distance of .
Answer
150.
Why not the others: '42' calculates only the distance at initial velocity (), omitting the acceleration displacement; '258' omits the factor of on the acceleration term, calculating ; '156' is an arithmetic error in applying .
