A ball's projected at an angle X to the horizontal from a cliff 96 metres high and strikes the ground at a distance of 260 metres away from the cliff.The time of its flight is 7 seconds.If it's assumed that air resistance's negligible,calculate: 1.the initial vertical velocity of the ball, 2.the time to reach the greatest height, 3.the initial horizontal velocity, 4.the angle X,and, 5.the velocity of the projectile on hitting the ground.
