Question
A batsman hits a sixer, and the ball touches the ground outside the cricket ground. Which of the following graph describes the variation of the cricket ball’s vertical velocity with time between the time as it hits the bat and time when it touches the ground?
The correct answer is:
At time the velocity of ball will be maximum, and it goes on decreasing with respect to time
At the highest point of path its velocity becomes zero, then it increases but direction is reversed
This explanation matches with graph [c]
