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 displacement $x$ in time $T$ satisfies $- v_0T < x < v_0T$

Answer 2

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