If the speed is not zero then the displacement of an object cannot be
Positive
Negative
Zero
None of these.
The displacement time graph can
have sharp turns?
can't have sharp turns?
can be circular.
None of these.
If the instantaneous velocity is zero then we can say that,
Displacement is zero?
Acceleration is zero.
Path length is zero.
Instantaneous speed is zero.
Is it possible that displacement-time graph be a sine or cosine function?
Yes
No
The displacement of an object varies as
X=at (1 - bt),
What is the distance travelled when from t=0 to the time when the displacement again becomes zero.
a 2b
a 4b
0
