The correct statement from the following is
View answer and explanation
Correct option: A
A body having zero velocity will not necessarily have zero acceleration
Option A is correct because a body can have zero velocity at an instant while still experiencing acceleration, such as at the peak of its trajectory when thrown upwards.

Assertion: In a free fall, the initial velocity of a body may not be zero.
Reason: Free fall means the vertical acceleration of the body is equal to . A ball is thrown vertically upward with speed 15 m/s and it returns to the ground with speed 10 m/s as a constant air resistance acts. The maximum height attained by the ball is Which of the following is not a derived quantites? Assertion: If a body is dropped from the top of a tower of height and another body is thrown up simultaneously with velocity from the foot of the tower, then both of them would meet after a time .
Reason: For a body projected upwards, the distance covered by the body in the last second of its upward journey is always irrespective of velocity of projection. A particle is having uniform acceleration. If its displacement from to second is and change in velocity is . Find its displacement (in ) in second. An aeroplane flies 400m north and 300m south and then flies 1200m upwards, then net displacement is
