Questions
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 -v0T< x < voT
c
The acceleration is always a non-negative number
d
The motion has no turning points
detailed solution
Correct option is B
For maximum and minimum displacement we have to keep in mind the magnitude and direction of maximum velocity. As maximum velocity in positive direction is vo maximum velocity in opposite direction is also vo. Maximum displacement in one direction = voT Maximum displacement in opposite direction = -voT. Hence, -voT < x < voTTalk to our academic expert!
