Question

In one dimensional motion, instantaneous speed $ v $ satisfies $ 0 \le v < v_0 $ .

• A. The displacement in time $ T $ must always take non-negative values
• B. The displacement $ x $ in time $ T $ satisfies $ - v_0T < x < v_0T $
• C. The acceleration is always a non-negative number
• D. The motion has no turning points

Answer 1

Answer: (B)

The maximum distance covered in time $ T=v_0T $ . Therefore, for the object having one dimensional motion, the displacement $ x $ in time $ T $ satisfies $ - v_0T < x < v_0T $ .
