easy
The correct statement from the following is
A
A body having zero velocity will not necessarily have zero acceleration
B
A body having zero velocity will necessarily have zero acceleration
C
A body having uniform speed can have only uniform acceleration
D
A body having non-uniform velocity will have zero acceleration
Solution
(a)When the body is projected vertically upward then at the highest point its velocity is zero but acceleration is not equal to zero $(g = 9.8m/{s^2})$.
