Question

In one dimensional motion, instantaneous speed v satisfies $0 \leq v < v_{0}.$

• A. The displacement in time T must always take non-negative values
• B. The displacement x in time T satisfies $- v_{0}T < x < v_{0}T.$
• 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 $- v_{0}T < x < v_{0}T.$

Answer 2

The maximum distance covered in time $T = v_{0}t.$ Therefore, for the object having one dimensional motions, the displacement x in the T satisfies $- v_{0}T < x < v_{0}T.$
