Important Questions on Kinematics
A balloon is moving up in air vertically above a point on the ground. When it is a height a girl standing at a distance d (point B) from A (see figure) sees it at an angle with respect to the vertical. When the balloon climbs up a further height , it is seen at an angle with respect to the vertical if the girl moves further by a distance (point C). Then the height is (given ):


The velocity and time graph of a body in a straight line motion is shown in the figure. The point is at seconds. The total distance covered by the body in is :

A clock has a continuously moving second's hand of length. The average acceleration of the tip of the hand (in units of ) is of the order of :
