Statement I: For a particle moving is a straight line, velocity ( 
in 
) of the particle in terms
of time ( 
in sec) is given by 
. Then the speed of the particle is minimum at 
.
Statement II: For a particle moving in a straight line the velocity 
at any time 
may be minimum or may be maximum, when 
.
In the light of the above statements, choose the most appropriate answer from the options given below
Text Solution
Verified by ExpertsD
Both Statement I and Statement II are correct.
The expression for velocity and time can be expressed as
The speed is therefore zero at 
and 
.
Hence, speed is maximum at 
.
But 
is zero at 
.
