In one dimensional motion, instantaneous speed v satisfies
(a) The displacement in time T must always take non-negative values.
(b) The displacement x in time T satisfies –
(c) The acceleration is always a non-negative number.
(d) The motion has no turning points.
The correct answer is the option (b) The displacement x in time T satisfies -
Explanation: The magnitude & direction of max. & min. velocity can be used to determine the max. & min. displacement.
v0 is the maximum velocity in the positive direction as well as in the opposite direction (or we can say minimum velocity).
Thus, v0T is the maximum displacement in the positive direction & -v0T is the maximum displacement in the opposite direction.
Thus, -
