Q 5. A stone is thrown in a vertically upward direction with a velocity of . If the acceleration of the stone during its motion is in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
Taking upward direction as positive (+) direction:
(This is due to gravitational force!)
The stone will move up until its velocity becomes zero.
Therefore, the stone reaches to a height of
Therefore, the time taken by the stone to reach the maximum height is .
