From the top of a tower, two balls are thrown horizontally with velocities `u_(1)` and `u_(2)` in opposite directions. If their velocities are perpendicular to each other just before they strike the ground, find the height of tower.

From the top of the tower, two balls are thrown horizontally in opposite directions with velocities u_(1) and u_(2) . Find the distacne between the balls at the moment when their velocity vectors becomes mutually perpendicular. (Assume the height of tower very large)

Two balls are thrown horizontally from the top of a tower with velocities v_(1) and v_(2) in opposite directions at the same time. After how much time the angle between velocities of balls becomes 90^(@) ?
