1) A stone is projected upwards at an angle of 30° to the horizontal from the top of a tower of
height 100m and it hits the ground at a point Q. If the initial velocity of projection is 100ms
calculate the:
i. Maximum height of the stone above the ground;
ii. Time it takes to reach this height,
Time of flight
iv. Horizontal distance from the foot of the tower to the point Q. [Neglect air resistance and
take g as 10ms ?).
