Questions
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 -V0T < x < V0T.
c
The acceleration is always an non negative number
d
The motion has no turning points.
detailed solution
Correct option is B
Since 0 ≤ speed < v0, The particle may move along positive x - axis or along negative x - axis and magnitude of average velocity is less than v0, so magnitude of displacement is less than v0T and displacement may be positive or negative, so option (2) is right.Talk to our academic expert!
