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

Answer and explanation

Correct answer: B. 16

  1. Step 1: Displacement under constant acceleration is determined by the kinematic equation .
  2. Step 2: Substitute initial velocity , acceleration , and time : .
  3. Step 3: Computing the terms gives .
Answer
16.
Why not the others: 10 computes only ; 22 computes (forgets factor of ); 18 computes .
