Q8. A cricketer hits a cricket ball from the ground so that it goes directly upwards. If the ball takes, 10 s to return to the ground, determine its maximum height.
Answer : Option D
Explaination / Solution:
We know that at the maximum height, the velocity of the ball is 0 m/s.
We also know that the ball takes the same time to reach its maximum height as it takes to travel from its maximum height to the initial position, due to time symmetry. The time taken is half the total time.
Therefore, we have the following information for the second (downward) part of the motion of the ball:
t = 5 second; half the total time
g = 9.8 m/s2 downward
s = ?
As we know
s = ut+
Put all the given value,
=> s =
=> s = 122.5 m
