[" stones are projecte "],[" mum heights above "]

Two stones are projected from level ground. Trajectory of two stones are shown in figure. Both stones have same maximum heights above level ground as shown. Let T_(1) and T_(2) be their time of flights and u_(1) and u_(2) be their speeds of projection respectively (neglect air resistance). then

Two stones are projected so as to reach the same distance from the point of projection on a horizontal surface. The maximum height reached by one exceeds thr other by an amount equal to half the sum of the height attained by them. Then angle of projection of the stone which attains smaller height is

A stone is projected at an angle alpha to the horizontal from the top of a tower of height 3h. If the stone reaches a maximum height 'h', above the tower, show that it reaches the ground at a distance 6h cot alpha from the foot of the lower.

A stone is projected at an angle alpha to the horizontal from the top of a tower of height 3h If the stone reaches a maximum height h above the tower, then calculate the distance from the foot of the tower where particle strikes the foot of the where particle strikes the ground.

Two stones are projected with the same speed but making different angles with the horizontal. Their reanges are equal. If the angles of projection of one is pi//3 and its maximum height is h_(1) then the maximum height of the other will be:

Two stones are projected with the same speed but making different angles with the horizontal. Their horizontal ranges are equal. The angle of projection of one is pi/3 and the maximum height reached by it is 102 m. Then the maximum height reached by the other in metres is
