1.	The given acceleration-time graph represents which of the following physical situation? A. A cricket ball moving with a uniform speed is hit with a bat for a very short time interval.B. A ball is falling freely from the top of a tower.C. A car moving with constant velocity on a straight road.D. A football is kicked into the air vertically upwards.
Answer» Correct Answer - A The a-t graph shows that initially the body moves with uniform velocity. Its acceleration increases for a short time and then fails to zero and there after the body moves with a constant velocity. Such as physical situation arises when a cricket ball moving with a uniform speed is hit with a bat for a very short time interval.
