A car with an initial speed of accelerates at for . How far does it travel (in m)?
Answer and explanation
Correct answer: C. 114
- Step 1: Displacement under constant acceleration is determined by the kinematic equation .
- Step 2: Substitute initial velocity , acceleration , and time : .
- Step 3: Computing the terms gives .
Answer
114.
Why not the others: 6 computes only ; 222 computes (forgets factor of ); 120 computes .
