A stone is projected upwards at an angle of 30 degree to the horizontal from the top of a tower of height 100m and it hit the ground at a point Q. if the initial velocity of projection is 100m-1. calculate the ; (I) maximum height if the stone above the ground (ii) time it fakes to reach this height (iii) time if flight (iv) horizontal distance from the foot of the tower to the point Q. (Neglect air resistance and take g as 10ms-2)?
