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

Answer and explanation

Correct answer: A. 48

**
  1. Step 1: Under uniform acceleration, displacement is given by the kinematic relation .
  2. Step 2: Insert the given values , , and : .
  3. Step 3: Evaluating the arithmetic gives .
Answer
48.
Why not the others: '52' is an arithmetic error in applying ; '80' omits the factor of on the acceleration term, calculating ; '16' calculates only the distance at initial velocity (), omitting the acceleration displacement.
