In one dimensional motion, instantaneous speed `v` satisfies `(0 le v lt v_0)`.

Options

A. The displacement in time T must always take non-negative values.
B. The dispalcement x in time T satisfies `v_(0)Tltxltv_(0)T`
C. The acceleration is always a non-negative number
D. the motion has no turning points.

Answer

B

Explanation

We should not confuse with direction of velocities i.e., in one diretion it is taken as positive and in another direction is taken as negative.
