A car with an initial speed of accelerates at for . How far does it travel (in m)?
Answer and explanation
Correct answer: B. 56
**
- Step 1: The distance covered under constant acceleration is .
- Step 2: With , , and , write .
- 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 .
