A car with an initial speed of accelerates at for . How far does it travel (in m)?
Answer and explanation
Correct answer: C. 64
**
- Step 1: Apply the displacement-time formula .
- Step 2: Plug in , , and : .
- Step 3: Calculating both terms yields a total distance of .
Answer
64.
Why not the others: '68' is an arithmetic error in applying ; '112' omits the factor of on the acceleration term, calculating ; '16' calculates only the distance at initial velocity (), omitting the acceleration displacement.
