Question:
In one dimensional motion, instantaneous speed v satisfies 0 < v < v0
(a )The displacement in time T must always take non-negative values.
(b) The displacement x in time T satisfies -v()T < x < v0
(c) The acceleration is always a non-negative number.
(d) The motion has no turning points.
Solution:
The correct answer is (b) the displacement in time T must always take non-negative values
