The given acceleration-time graph represents which of the following physical situations?
A cricket ball moving with a uniform speed is hit with a bat for a very short time interval
A ball is falling freely from the top of a tower
A car moving with constant velocity on a straight road
A football ball is kicked into the air vertically upwards
A cricket ball moving with a uniform speed is hit with a bat for a very short time interval
Solution
The a – t graph show that initially the body moves with uniform velocity. Its accelerations increases for a short time and then falls to zero and their after the body moves with a constant velocity. Such a physical situations arises when a cricket ball moving with a speed is hit with a bat for a very short time interval.
