Q. The acceleration of a particle is zero at $t = 0$. Then choose the incorrect option :-
Motion in a Straight Line
A
Its velocity must be constant
B
The speed at t = 0 may be zero
C
If the acceleration is zero from t = 0 to t = 5s, the speed is constant in this interval
D
If the speed is zero from t = 0 to t = 5s, the acceleration is also zero in this interval
Solution:
Correct answer is (a) Its velocity must be constant
